Question

Q11. a) State the universal law of gravitation. b) Mass of an object is 20 kg.
Find its weight on earth. What will be its weight when measured on the
surface of the moon? c) What will be the effect on
gravitational force (F):
(i) if distance between two objects (r) is reduced to 1/4th ,and (ii)if the
masses of both the object is increased by 3 times?​

Answer 1

Answer:

i) Newton's law of gravitation, statement that any particle of matter in the universe attracts any other with a force varying directly as the product of the masses and inversely as the square of the distance between them.

ii)Since , weight on moon is 1/6 weight on earth. Therefore , weight on moon is 32.6 Newton ( N ).
