Page: + At what height from surface of earth accelaration
due to gravity is half of the surface

(R=6. 4×106m)

Explanation:

The height above the surface of earth at which acceleration due to gravity is half the acceleration due to gravity at surface of earth

Explanation:

acceleration due to gravity at surface of earth is (R=6. 4×106m)

hope this answer helps you

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
