A positively charged thin metal ring of ...

A positively charged thin metal ring of radius R is fixed in the xy plane with its centre at the origin O. A negatively charged particle P is released from rest at the point `(0, 0, z_0)` where `z_0gt0`. Then the motion of P is

Text Solution

Verified by Experts

A negatively charged particle will perform an oscillatory motion. It will be S.H.M if the particle is released at a distance very small in comparison to the radius of the ring
