372124 A body is sliding down an inclined plane having coefficient of friction 0.5 . If the normal reaction is twice that of the resultant downward force along the inclination the angle between the inclined plane and the horizontal is

1 \(15^{\circ}\)
2 \(30^{\circ}\)
3 \(45^{\circ}\)
4 \(60^{\circ}\)

372125 A particle is projected up along a rough inclined plane of inclination \(45^{\circ}\) with the horizontal. If the coefficient of friction is 0.5 , the acceleration is

1 \(\frac{g}{2}\)
2 \(\frac{g}{2 \sqrt{2}}\)
3 \(\frac{3 g}{2 \sqrt{2}}\)
4 \(\frac{g}{\sqrt{2}}\)

372126 A body is sliding down a rough inclined plane. The coefficient of friction between the body and the plane is 0.5 . 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

1 \(15^{\circ}\)
2 \(30^{\circ}\)
3 \(45^{\circ}\)
4 \(60^{\circ}\)
LAWS OF MOTION (ADDITIONAL)

372127 When the angle of inclination of an inclined plane is \(\theta\), an object slides down with uniform velocity. If the same object is pushed up with a initial velocity \(u\) on the same inclined plane; it goes up the plane and stops at a certain distance on the plane. Thereafter the body

1 slides down the inclined plane and reaches the ground with velocity \(u\).
2 slides down the inclined plane and reaches the ground with velocity less than \(u\).
3 slides down the inclined plane and reaches the ground with velocity greater than \(u\).
4 stays at rest on the inclined plane and will not slide down.
