A research satellite of mass 200 kg. circles the earth in an orbit of average radius 3R/2  where R is radius of earth. Assuming the gravitational pall 10N, the pull on the satellite will be...N

If the value of ' g ' acceleration due to gravity, at earth surface fs .10ms^-2 its value in ms^-2 at the center of earth, which is assumed to be a sphere of Radius ' R ' meter and uniform density is

A man can jump to a height of 1.5 m on a planet  Α what is the height ne may be able to jump on another planet whose density and radius are respectively one- quater and one- third that of planet A

If density of earth increased 4 times and its radius becomes half of then out weight will be...

Weight of body of mass m decreases by 1% when it is raised to height h above the earth's surface. If the body is taken to a depth h in a mine. change in its weight is

Density of the earth is doubled keeping its radius constant then acceleration, due to gravity will. be …….ms^-2 (g=9.8 ms²)

The acceleration due to gravity is  at a point distance r from the center of earth . if . R.  if r<R.then

If then

The variable v is used just for simplification. When we take partial derivative w.r.t to certain variable, we keep other variables constant.
