- A Van de Graaff generator is meant to collect a large amount of charge on a spherical conductor. Explain why the spherical shape of the conductor is important for collecting as much charge as possible.By the time he was forty years old, Benjamin Franklin had made enough money in various business enterprises to live comfortably for the rest of his life. At this time he decided to devote his energy to scientific investigations. It wasn’t until he was nearly 50 years old that he began his career as a statesman. When he was experimenting with atmospheric electricity and lightning, Franklin naturally wanted to know when a charged thundercloud was approaching. He set up the alarm shown here. Briefly explain how it worked.#2 (a) The fundamental SI units are meters for length, seconds for time, kilograms for mass, andCoulomb for charge. Use the Coulomb force law for two interacting point charges (F = kq1q2/r2)and the force units you already know from mechanics (N) to find the SI units for Coulomb’sconstant k and the constant 0 = 1/4πk. Express your answers using only the four fundamentalunits. (b) What are the units of the electric field, expressed first using force units (N) and then using onlyfundamental SI units? (c) Visualizing how an electric field varies with location is going to prove very helpful. Using arrowsat several test points in the xy plane - enough points to illustrate the behavior of the fields -sketch the following electric fields at the test points and briefly describe the behavior of the fieldin words. You only need to provide a qualitatively correct plot that is consistent with the vectorfunction and the description - you don’t need to calculate the vectors although I will show…
- You are told that in a thundercloud, a 0.75 g raindrop can acquire a charge of 1.1 mC. Assume that two such raindrops are separated by 4.9 cm. What is the acceleration, in meters per square second, of each raindrop away from each other? The numbers provided seem to be reasonable - why should you not believe the source of this information? Which premise or assumption is responsible for the error?Problem 3: Consider the arrangement of three identical small charged spheres, each of mass 6.2 g and charge 53.4 nC, as shown in the figure. The charges are positioned at the vertices of an equilateral triangle with side lengths of 68.6 cm. V = 9 m/s a 9 a a ▲ If these spheres are released from rest at precisely the same time, how fast, in meters per second, will they be moving when they are infinitely far away from each other? 9 Otheexpertta.comA particle (q = 5 mC, m 5 mC, m = 20 g) has a speed of 13 m/s when it enters a region where the electric field has a constant magnitude of 43 N/C and a direction that is the same as the speed of the particle What is the particle's velocity 5 s after it enters this region? From your answer without a decimal place.
- An electron with speed v0 = 3388829.6m/s travels parallel to and along the same direction as an electric field of magnitude E = 3154N/C. (a) How far will the electron travel before it stops? Answer in SI units and multiply your answer by 10^2. (b) How much time will elapse before it returns to its starting point? Answer in SI units and multiply your answer by 10^8.A charged ion with charge of +2.65 x 10-19 C and a mass of 3.15 x 10-27 kg is held halfway between two oppositely charged plates with voltage of 3.06 x 104 V. What is the maximum speed the ion will attain when let go and allowed to accelerate? Provide your answer to three significant digits, without units. Answer:Since 180 kV voltage is applied to a system with planar electrodes with three insulating layers (Sı=S2=S3=10 cm²) as shown in the figure. a) Calculate the stresses and electric field strengths in the layers. b) Calculate the capacity of the system (Eo=8,854x10-12 F/m). c) Show if the whole system can be pierced. Find the highest stress that can be applied without puncture in any layer of the system and the highest stress that the system will withstand even if there is a break in any layer? a1 = 1,4 cm &rl = 1 Ea1 = 30 kV/cm az = 1,8 cm &2 = 4 Ea2 = 100 kV/cm az = 3,2 cm &r3 = 3 Ed3 = 70 kV/cm %3D %3D LU= 180 kV 1 2
- A proton has a mass of about 1.673x10-27kg. If an electron is placed in a region of space within which a constant electric field exists with magnitude 4.156 N/C, how long would it take this proton to travel a distance of 649.72m in units of ms (milliseconds)? Assume the proton does not collide with anything along the way. Hint: You will need to use the kinematic relationships for linear motion that we learned back in PHY 2010. This results of this problem show you that small charges like protons, and electrons too, move great distances in a short amount of time under very small external electric fields - if those charges are in a vacuum - otherwise, they quickly strike a nearby charge.Can you charge an insulator by induction? What happens to a wooden stick when you rub it against your hair? Explain how you got your answers.simple and common technique for accelerating electrons is shown in the figure below, where there is a uniform electric field between two plates © L 39% Electrons are released, usually from a hot filament, near the negative plate, and there is a small hole in the positive plate that allows the electrons to continue moving. (a) Calculate the acceleration in meters per second squared of the electron if the field strength is 3.20 x104 N/C. m/s2 (b) Explain why the electron will not be pulled back to the positive plate once it moves through the hole.
