Assertion: When distance between bodies ...

Assertion: When distance between bodies is doubled and also mass of each body is also doubled, gravitational force between them remains the same.
Reason: According to Neweton's law gravitational, force is directely proportional to mass of bodies and inversely proportional to square of distance between them.

A

If both assertion and reason are true and reason is the correct explanation of assertion

B

If both assertion and reason are truebut reason is not the correct explanation of assertion

C

If assertion is true but reason is false

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
A
(a) According to Newton's law of gravitation, `F=(Gm_(1)m_(2))/(r^(2))`. When `m_(1),m_(2)` and r all are doubled, `F=(G(2m_(1))(2m_(2)))/((2r)^(2))=(Gm_(1)m_(2))/(r^(2))`, i.e. F remains the same.
