An inclined plane making an angle of `30^o` with the horizontal is placed in an uniform electric field `E = 100 Vm^(–1)`. A particle of mass 1 kg and charge 0.01 c is allowed to slide down from rest from a height of 1m. If the coefficient of friction is 0.2 the time taken by the particle to reach the bottom is .......... sec.
