Two point masses A and B having masses in the ratio `4:3` are separated by a distance of 1m. When another point mass C of mass M is placed in between A and B, the force between A and C is `(1/3)^(rd)` of the force between B and C. Then the distance C from A is

Two bodies A and B having masses 20kg and 40kg are separated by 10 m. at what distance from body a should another body C of mass 15 kg be placed so that net gravitational force on C is zero?

Two point masses m and M are separated bya distance L . The distance of the centre of mass of the system from m is

A body of mass 50 kg and another body of mass 60 kg are separated by a distance of 2 m. What is the force of attraction between them?

Gravitational force between two point masses m and M separated by a distance r is F . Now if a point mass 3m is placed very next to m , the total force on M will be

The particles A and B of mass m each are separated by a distance r . Another particle C of mass M is placed r . Another particle C of mass M is placed at the midpoint of A and B . Find the work done in taking C to a point equidistant r form A and B without acceleration (G = Gravitational constant and only gravitational constant and only gravitational intereaction between A, B and C is considered )

Gravitational force between a point mass m and M separated by a distance is F. Now if a point mass 2m is placed next to m is contact with it. The force on M due to m and the total force on M are
