Answer 1

Answer:

Question:-

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

Solution:-

Acceleration due to gravity at a height h from the surface of the earth

• g′=g/[1(1+h/R)2]

• Given h = 2R

• ∴ g′=g[1/(1+2)2]

• or g′ = g/9.
