The radius of the earth is 6400 km and g = 10 ms^−2. In order that the body of 5 kg weighs zero at the equator, the angular speed of the earth is the angular speed of the earth is The radius of the earth is 6400 km and g = 10 ms^−2. In order [...]
A spherical shell is cut into two pieces along a chord as shown in the figure. P is a point on the plane of the chord. The gravitational field at P due to the upper part is I1 and that due to the lower part is I2. What is the relation between them?

A skylab of mass m kg is first launched from the surface of the earth in a circular orbit of radius 2R(from the centre of the earth) and then it is shifted from this circular orbit to another circular orbit of radius 3R. The minimum energy required to place the lab in the first orbit and to shift the lab from first orbit to the second orbit are.
