Answer 1

Answer:

a = yes

b = yes

c = yes

d = no

e = yes

Answer 2

(a) True

As every body in the universe attracts other bodies, so a falling stone also attracts the earth.

(b)  False

The force of gravitation between two objects does not depend upon the nature of medium between them.

(c)  False

G is gravitational constant, so its value will not change.

(d) False

The acceleration due to gravity does not depend on the mass of the object.

(e)  False

Actually, the weight of an object on the earth is about six times of its weight on the moon.
