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 values of `z_(o)`satisfying `0ltz_(o)ltoo`

B

Simple harmonic for all values of satisfying `0 lt z_(o) lt R`

C

Approximately simply harmonic provided `z_(o)ltltR`

D

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