The figure shows a region containing a uniform magnetic field B, which is increasing at the rate `(dB)/(dt)` The region is gravity free. A disc of mass m and radius R is kept in this magnetic field. Two charged particles having charge `q_1 and q_2` and masses m and 2m are embedded to the non-conducting disc on the circumference at diametrically opposite points. The disc is free to translate as well as rotate.

If `q_1 = -q and q_2 = q` , then the initial acceleration of `q_1` will be

A

`(qR)/(3m) (dB)/(dt)`

B

`(2qR)/(3m) (dB)/(dt)`

C

`(2qR)/(m) (dB)/(dt)`

D

`(qR)/(m) (dB)/(dt)`
