Define G and g. how are they telated to eachother ? Use this relation to calculate mass of earth.

Define 'g' and 'G'. Establish relation between the two. How do you use this relation to calculate mass of earth ?

If two isolated spherical conductor each having a define capacity are far apart and are connected to eachother by a fine wire, how do you calculate the capacity of the combination ? In joining them with wire, have connected them in parallel or in series ?

The speed v of a satellite moving in a circular orbit around the earth depends on the gravitational constant G , mass of the earth m_(e) and radius of circular orbit r . Estabish the relation using dimensions.

g_(e) and g_(p) denote the acceleration due to gravity on the surface of the earth and another planet whose mass and radius are twice as that of earth. Then

A satellite of mass m is in a circular orbit of radius r round the Earth. Calculate its angular momentum with respect to the centre of the orbit in terms of the mass M of the Earth and G .

What is the relation between g and G ?
