An inclined plane of length `5.60` m making an angle of `45^(@)` with the horizontal is placed in a uniform electric field `E=100 Vm^(-1)`. A particle of mass `1 kg` and charge `10^(-2)C` is allowed to slide down from rest position from maximum height of slope. If the coefficient of friction is 0.1, then the time taken by the particle to reach the bottom isA. 1 sB. 1.41 sC. 2 sD. None of these |
