Calculate the orbital velocity and time period of rotation of a planet rotating in circular path about the sun.

Show that the time period of revolution for any planet T^2propr^3 [r = radius of the circular path]

Define escape velocity.Deduce anexpression for the escape velocity and time period of a body that moves in a circular orbit near the earth's surface.

Suppose the gravitational force varies inversely as the n th power of the distance. Thus the time period of a planet moving in a circular orbit of radius r around the sun will be proportional to

Find out the orbital velocity of mass 'm' rotating around sun of mass M with radius of the orbit r.

A charged particle enters a magnetic field vec(B) perpendicularly with velocity v and keeps rotating along a circular path of radius r. What will happen if the magnitude of vec(B) is increased?

The earth rotates around the sun in a circular orbit of radius R. Calculate the orbital speed of rotation of the earth around the sun. Also find the time period of rotation. Take the mass of the earth =m, mass of the sum =M.
