Answer 2

Answer:

(a) Acceleration decreases according to formula g

′

=g(1−

R

2h

),

where h is height and R is radius of earth.

(b) Acceleration decreases according to formula g

′

=g(1−

R

d

),

where d is depth and R is radius of earth.

(c) Acceleration due to gravity is given by the formula: g=

R

e

Hence, it is independent of mass of body, but is dependent on mass of earth.

(d) Gravitational potential energy is given by the formula: U=−

r

Gm

g=

assuming distance between object and earth is nearly equal to the radius of the earth.

Substituting the second equation in first, we get U≈mgh

Hence, the first formula is more accurate.
