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. (a) `(1)/(2)(eR)/(m)(dB)/(dt)` toward leftB. (b) `(1)/(2)(eR)/(m)(dB)/(dt)` toward rightC. ( c) `(eR)/(m)(dB)/(dt)` toward leftD. (d) zero |

Answer» Correct Answer - A (a) Induced electric field at point `P`: `E = (R )/(2)(dB)/(dt)` towards right acceleration of electron: `a = (eE)/(m) = (eR)/(2m)(dB)/(dt)` towards left |
