Mass particles of 1 kg each are placed along x-axus at `x=1, 2, 4, 8, .... oo`. Then gravitational force o a mass of 3 kg placed at origin is (G= universal gravitation constant) :-

Infinite number of masses, each of 1 kg , are placed along the x-axis at x = +- 1m, +- 2m, +-4m, +- 8m, +- 16m .. The gravitational of the resultant gravitational potential in term of gravitaitonal constant G at the origin (x = 0) is

A large number of identical point masses m are placed along x - axis ,at x = 0,1,2,4, ……… The magnitude of gravitational force on mass at origin ( x =0) , will be

A large number of identical point masses m are placed along x - axis ,at x = 0,1,2,4, ……… The magnitude of gravitational force on mass at origin ( x =0) , will be

Two particles of masses 1 kg and 2 kg are placed at a separation of 50 cm find out gravitational force between them
