When a constant torque is applied on a rigid body, then
When a capillary tube is dipped in a liquid, the liquid rises to a height $h$ in the tube. The free liquid surface inside the tube is hemispherical in shape. The tube is now pushed down so that the height of the tube outside the liquid is less than $h$. Then the
When a capillary tube is immersed into a liquid the liqaid neither rises nor falls in the capatillary , then the angle of contact is
When a body slides down from rest along a smooth inclined plane making an angle of $45^?$ with the horizontal, it takes time $T$. When the same body slides down from rest along a rough inclined plane making the same angle and through the same distance, it is seen to take time $pT$, where $p$ is some number greater than $1$. The co-efficient of friction between the body and the rough plane is
