Q11 of 49 Page 10

Two electrons, each having mass 9.1 × 10-31 kg, are separated by a distance 10 Å. Calculate the gravitational force between them.


Given,
mass of electron(me)= 9.1 × 10-31 kg
distance between them(r)= 10 Å=10 × 10-10 m
G=6.673 × 10-11 N m2 kg-2
The gravitational force between them(Fg) is given by,

How does the force of gravitation between two objects change when the distance between them is reduced to half?

10

Gravitational force acts on all objects in proportion to their masses. Why then, a heavy object does not fall faster than a light object?

(a) A book has a mass 400 g. Find its weight when taken from the surface to a height equal to the radius of the earth.
(b) Define weight.

14

Distinguish between mass and weight of a body. When does a body experience weightlessness?
