A charge particle moves in a circle around an infinite line charge with the center of circle at the line and line being perpendicular to the plane of circle. Let r be the radius of circle. The velocity of the particle depends upon which power of r.

A

1

B

2

C

`-1`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
D
`(lamdaq)/(2piepsilon_(0)r)=(mv^(2))/(r)` or `v=sqrt((lamda)/(2piepsilon_(0)mq))` independent of r
