A geostationary satellite is revolving around the earth. If the radius of the earth is ‘R’ and the angular speed about its own axis is ‘w’ then, the radius of the orbit of the geostationary satellite is:

The escape velocity for a planet whose mass is six times the mass of earth and radius is twice the radius of earth will be. (V= escape velocity from the earth)

Consider earth to be a sphere of radius R rotating about its own axis with angular speed w ‘ge’ and ‘gp’ are the accelerations due to gravity at the equator and the poles respectively, then (gp – ge) is given by:

A body of mass ‘m’ is dropped from a height R/2 from earth’s surface where R is the radius of earth. Its speed when it will hit the earth’s surface is: (V= escape velocity from earth’s surface)

The mass and radius of earth is Me and Re respectively and that of moon is Mm, and Rm respectively. The distance between the centre of earth and that of moon is ‘D’. The minimum speed required for a body (mass ‘m’) to project from a point midway between their centers to escape to infinity is:

A body is projected vertically upwards from earth’s surface. If its kinetic energy of projection is equal to half of its minimum value required to escape from earth’s gravitational influence then the height upto which it rises is: (R = radius of earth)

If the distance between the sun and the earth is increased 3 times, then attraction between sun and earth will:

At what height from the earth’s surface, the gravitational potential and the value of gravitational acceleration are 5.4 x 10^7 J/kg^2 and 6.0 m/s^2 respectively? (Radius of earth = 6400 km)

Assuming earth to be a sphere of radius R, if g30 degree. is value of acceleration due to gravity at latitude of 30° and g at the equator, the value of g – g30 degree is

If mass of a body is M on the earth surface, then the mass of the same body on the moon surface is
