A uniform magnetic field of induction B is confined to a cylindrical region of radius R. The magnetic field is increasing at a constant rate of \[\frac{dB}{dt}\] (tesla/second). An electron of charge q, placed at the point P on the periphery of the field experiences an acceleration.

A) \[\frac{BR}{(\sqrt{2}+1)m}\] towards left

B) \[\frac{1}{2}\,\frac{eR}{m}\,\frac{dB}{dt}\] towards left

C) \[\frac{eR}{m}\frac{dB}{dt}\] towards left

D) zero
