Top Questions on Acceleration due to gravity of the earth
- What is the value of acceleration due to gravity at a height equal to half the radius of the Earth, from its surface ?
Choose the correct alternative :
(a) Acceleration due to gravity increases/decreases with increasing altitude.
(b) Acceleration due to gravity increases/decreases with increasing depth (assume the earth to be a sphere of uniform density).
(c) Acceleration due to gravity is independent of mass of the earth/mass of the body.
(d) The formula –G Mm \(\frac{1}{r_2 }– \frac{1}{r_1}\) is more/less accurate than the formula mg(r2 – r1) for the difference of potential energy between two points r2 and r1 distance away from the centre of the earth.- CBSE Class XI
