If both speed of a body and radius of the circular path are doubled, what will be the change in centripetal force?

If you double the radius of the capillary tube, what will be the drop in height rise in the tube?

If the mass of a body is halved and its velocity doubled, its momentum will not change. Explain.

A body is moving in a circular path with constant speed

In order to cause a body to move along a circular path we must supply :

If the number of molecules of a gas in a container is doubled what will be the affect on pressure and rms speed?

The length between two bridges of a sonometer wire is L, tension is T and the fundamental frequency is N, if the length between the bridges and tension both are doubled, explain if there is any change in fundamental frequency.

A satellite has mass m speed v and radius of circular orbit r. The force F acting on it is :

Show that the linear speed of a paricle rotaling alon a circular path is r times the angular speed of the particle.
