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 the mass of the earth/mass of the body.

(d) The formula –G M m($$\dfrac{1}{r_2}-\dfrac{1}{r_1}$$) 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.

##### Solution :-

(a) Acceleration due to gravity decreases with increasing altitude.

(b) Acceleration due to gravity decreases with increasing depth (assume the earth to be a sphere of uniform density).

(c) Acceleration due to gravity is independent of the mass of the mass of the body.

(d) The formula –G M m($$\dfrac{1}{r_2}$$ – $$\dfrac{1}{r_1}$$ more 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.
