The masses are charged with opposite charges. OFTENSION + F₁ g on m1 + Fe e q2 on 91 - One of the spheres can be neutral. 0 The charges on both masses have the same sign. The electric force between the charges depends on the length of the string. OFg on m₁ = Fe 1 on 2 | The absolute value of the charge has to be the same on both masses. The value of the angle a depends on the length of the string.
