The radius of Jupiter is 11 times the radius of the Earth . Calculate the ratio of the volumes of Jupiter and the Earth. How many Earths can be Jupiter accommodate ?

If M is the mass of the earth and R its radius, the ratio of the gravitational acceleration and the gravitational constant is

If both the mass and radius of the earth decreases by 1% then the

A mass m on the surface of the Earth is shifted to a target equal to the radius of the Earth. If R is the radius and M is the mass of the Earth, then work done in this process is

A space station is at a height equal to the radius of the Earth . If v_E is the escape velocity on the surface of the Earth , the same the spastation v_E

The radius of a hydrogen atom is 5.32 xx10^(-11) m and the radius of a proton at the centre is 1.5 xx 10^(-5) m. The ratio of the radius of the atom to the radius of proton is :
