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 timeB. in the above situation, electron will experience the force in negative y-axisC. if a proton is kept at `(0, R/2,0)` and magnetic field is decreasing then it will experience the force in positive x-directionD. if a proton is kept at `(-R,0,0)` and magnetic field is increasing then it will experience force in negative y-axis |

Answer» Correct Answer - 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. |
