When the charged rod which was held near the top of a polarized electroscope is removed, the excess electrons at the top of the electroscope return to the leafs and the leafs of this electroscope return to the neutral position. Explain the behavior of electrons during this process in terms of forces acting on the electrons while the charged rod is near the electroscope and after the rod is removed.

overcharge is the right answer system

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
