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.

A track has two inclined surface AB and DC each of length 3 m and angle of inclination of 30^@ with the horizontal and a central horizontal part of length 4m shown in figure. A block of mass 0.2 kg slides from rest from point A. The inclined surfaces are frictionless. If the coefficient of friction between the block and the horizontal flat surface is 0.2, where will the block finally come to rest ? [in 10^(-1) m ]

When a body slides down from rest along a smooth inclined plane making an angle of 30^(@) with the horizontal, it takes time 20s. When the same body slides down from rest along a rough inclined plane making the same angle and through the same distance, it takes time 20p is, where p is some number greater than 1. The coefficient of friction between the body and the rough plane is
