The value of acceleration due to gravity at earth's surface is 9.8ms^-1 . The altitude above its surface at which the acceleration due to gravity decreases to 4.9ms^-2 ,is close to (Take,radius of earth =6.4*10^6 m )

The value of acceleration due to gravity at Earth's surface is 9.8ms^(-2) . The altitude (in metre) above its surface at which the acceleration due to gravity decreases to 4.9ms^(-2) , is close to :(Radius of earth =6.4xx10^(6)m )

The value of acceleration due to gravity at the surface of earth

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

As we go above the earth's surface , the value of acceleration due to gravity increases.

If R is the radius of the Earth then the height above the Earth's surface at which the acceleration due to gravity decreases by 20% is

At what height from the surface of earth, the acceleration due to gravity decreases by 2% ? [Radius of earth = 6,400 km.]

Acceleration due to gravity at earth's surface is 10ms^(-2) . The value of acceleration due to gravity at the surface of a planet of mass (1/5)^(th) and radius 1/2 of the earth is
