A man of mass $m$ starts falling towards a planet of mass $$M$$ and radius $$R$$. As he reaches near to the surface, he realizes that will pass throug...

What will be the acceleration due to gravity at a depth d, where g is acceleration due to gravity on the surface of earth?

From a solid sphere of mass M and radius R, a spherical portion of radius $${R \over 2}$$ is removed as shown in the figure. Taking gravitational pot...

If the earth stops rotating about its axis, then what will be the change in the value of g at a place in the equatorial plane? (Radius of earth = 6400...

Two spheres of the same material and same radii r are touching each other. The gravitational force between the spheres is proportional to

A satellite is moving around the earth with speed v in a circular orbit of radius r. If the orbit radius is decreased by 2%, its speed will increase b...
