Question

If g is the acceleration due to gravity on the surface of the earth, its value at a height equal to double the radius of the earth is, g, g 2, g 3, g 9

MARKS App · Accepted Answer

Acceleration due to gravity at a height h form the surface of the earth g ′ = g 1 1 + h R 2 G i v e n , h = 2 R ∴ g ′ = g 1 1 + 2 2 o r g ′ = g 9
