A uniform magnetic field of induction B ...

A uniform magnetic field of induction `B` is confined to a cyclindrical region of radius `R`. The magnetic field is increasing at a constant rate of `dB//dt` (tesla`//` second). A charge `e` of mass `m`, placed at the point `P` on the periphery of the fixed experiences an acceleration :

A

`(1)/(2)(eR)/(m)(dB)/(dt)` towards left

B

`(1)/(2)(eR)/(m)(dB)/(dt)` towards right

C

`(eR)/(m)(dB)/(dt)` toward left

D

`(1)/(2)(eR)/(m)(dB)/(dt)` zero
