Mass M is divided into two parts xM and (1 – x) M. For a given separation, the value of x for which the gravitational force between the two pieces becomes maximum is

Two particle of equal mass go round a circle of radius r. Under the action of their mutual gravitational force. The speed of each particle is =..................

The distance of the moon and earth is D the mass of earth is 81 times the mass of moon. At what distance from the centre of the earth, the gravitational force will be zero

One can easily “ Weight the earth ” by calculating the mass of earth using the formula (in usual notation)

Three equal masses of m kg each are placed the vertices of an equilateral triangle PQR and a mass of 2m kg is placed at the centroid 0 of the triangle which is at a distance of √2 m from each of vertices of triangle. The force in newton. acting on the mass 2m is = ............

Which of the follwing statement about the gravitational constant is true

Two point masses A and B having masses in the ratio 4 : 3 are separated by a distance of lm. When another point mass c of mass M is placed in between A and B the forces A and C is 1/3rd of the force between band C, Then the distance C form A is = ............... m
