Question

Two particles of masses m and M are placed at a
distance r. The ratio of gravitational force on mass
m due to mass M and on mass M due to mass
m is
1.M : m 2.M^2 : m^2
3.1 : 1. 3.m : M​

Answer 1

Answer :

The correct answer is option 3

1 : 1

Newton's 3rd law : when two massive bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction

Step-by-step Explanation :

Given : Two particles of masses m and M are placed at a distance r

To find : The ratio of gravitational force on mass m due to mass M and

on mass M due to mass m is = ?

The force exerted by mass M on mass m is given by,

Force 1 = GMm / r²

Also the force exerted by mass m on mass M is given by,

Force 2 = GMm / r²

Therefore Force 1/Force 2 = 1:1
