Question

gravitational force between 2 point masses m and M separated by a distance is F.now if point mass 3m is palced next to m,the total force on M will be..?

Answer 1

Every particle attract every other particle in the universe with a force which varies as the product of their masses and inversely as the square of the distance between them.

If the force of attraction exerted by M on m is denoted by F21 and the distance between them is denoted by F , then

Answer 2

Answer:

option (c)F,3F

Explanation:

The gravitational force on mass M due to mass m will remain same as it does not get effected by any other masses added to the system.

Therefore,Force on mass M due to m = F

Since, gravitation force is directly proportional to the product of masses the force on M due to 2m x 1m mass will be = 2F

Now,

The total force on mass M will be 2F + F = 3F
