Magnetic field in cylindrical region of ...

Magnetic field in cylindrical region of radius `R` in inward direction is as shown in figure.

A

an electron will expereince no force kept is `(2R,0,0)` if magnetic field increases with time

B

in the above situation, electron will experience the force in negative y-axis

C

if a proton is kept at `(0, R/2,0)` and magnetic field is decreasing then it will experience the force in positive x-direction

D

if a proton is kept at `(-R,0,0)` and magnetic field is increasing then it will experience force in negative y-axis

Text Solution

Verified by Experts

The correct Answer is:
B, C, D
If `ox` magnetic field increases, then induced electric lines are anti clockwie. If `ox` magnetic field decreases, then induced electric lines are clockwise (both inside and outside the cylindrical region).
On positive charge, force is the is in the direction of `E`. On negative chare, force is in the opposite.
