Solution

The correct option is A 12eRmdBdt toward left
At P induced electric field, Edl=d(AB)dtE(2πR)=(πR2)dBdt
When your right thumb points in the direction opposite to the change in B your curl fingers in the direction of the induced electric field.
E=R2dBdt...(towardright)
Acceleration, a=Fm=eEm=eR2mdBdt...(towardleft)
