270340 The minimum force required to move a body up on an inclined plane is three times the minimum force required to prevent it from sliding down the plane. If the coefficient of friction between the body and the inclined plane is\(\frac{1}{2 \sqrt{3}}\), the angle of the inclined plane is

270341 Starting from rest, the time taken by a body sliding down on a rough inclined plane at\(45^{\circ}\) with the horizontal is, twice the time taken to travel on a smooth plane of same inclination and same distance. Then the coefficient of kinetic friction is (2008 E)

270342 A body is sliding down a rough inclined plane. The coefficient of friction between the body and the plane is0.5 . The ratio of the net force required for the body to slide down and the normal reaction on the body is \(1: 2\). Then the angle of the inclined plane is
