Question

The distance moved by a particle in time t from center of a ring under the influence of its gravity is given by x = a sin wt ,w=omega=constant , a= constant . If w is found to depend on the radius of the ring,its mass and universal Gravitational constant G. Using dimensional analysis find an expression for w in terms of r,m and G.

Answer 2

Answer:

Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact.
