An inclined plane of length 5.60m making an angle of 45⁰ with the horizontal is placed in a uniform electric field E=100Vm⁻¹. A particle of mass 1kg and charge 10⁻²C is allowed to slide down from the 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 is
