The value of acceleration due to gravity `980cm//sec^2`. What will be its value if the unit length is kilometre & that of time is minute ?

What is the SI unit of acceleration due to gravity?

What do you mean by acceleration due to gravity ?

what is the value of acceleration due to gravity at the centre of the earth ?

The value of acceleration due to gravity of a planet having mass and radius twice those of the earth is.

What is the value of the acceleration due to gravity at the centre of the earth ?

What is the value of the acceleration due to gravity on the surface of the earth ?

At what height above the surface of the earth will the acceleration due to gravity be half of its value on the earth's surface ? Radius of the earth =6400 km.

Imagine earth to be a solid sphere of mass M and radius R. If the value of acceleration due to gravity at a depth d below earth's surface is same as its value at a height h above its surface and equal to (g)/(4) (where g is the value of acceleration due to gravity on the surface of earth), the ratio of (h)/(d) will be
