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

A

Periodic ,for all value of `z_(0)`satisfying `0 lt z_(0) oo`

B

Simple harmonic for all value of `z_(0)` satisfying `0 lt z_(0) le R`

C

Approximately simple harmonic ,provided `z_(0) lt lt R`

D

Such that `P` crosses `O` and continues to move along the negative "z-axis" towards `z-=-oo`
