a) b) Give an equation for the force F experienced by an electron travelling in vacuum at right- angles to a magnetic field B, and state its direction. Explain each term in the equation. Let the field be the Earth's magnetic field, at 4 x 10-5 T. The electron follows a circular path of radius 4 m. Find the speed of the electron, given that e/m for the electron is 1.759 × 10¹¹ Ckg-1.
