The centripetal force on a body in circular motion is given by `F=(mv^2)/r`.
Using the above formula, write an equation to find `%` error in centripetal force.

The centripetal force on a body in circular motion is given by F=(mv^2)/r . Write the dimension of force.

The centripetal force on a body in circular motion is given by F=(mv^2)/r . What is the number of significant figures in 0.050N ?

The centripetal force depends on mass of the body, velocity and radius of circular path. Find the expression for the centripetal force acting on the body using the principle of dimensional analysis. (Take constant k=1)

A physical quantity is given by h=(Fv^2)/L . F is the force, v is the velocity and L is the angular momentum. Find the dimensions of h.

Write the work done in each of the following cases as zero positive or negative. (a)Work done by centripetal force in circular motion. (b)Work done by friction. (c)Work done by gravitational force on a freely falling object. (d)Work done by the applied force in lifting an object.
