Two particles of masses `4kg` and `6kg` are separated by a distance of `20cm` and are moving towards each other under mutual force of attraction, the position of the point where they meet is

If two particles of masses 3kg and 6kg which are at rest are separated by a distance of 15 m . The two particles are moving towards each other under a mutual force of attraction. Then the ratio of distances travelled by the particles before collision is

10 Two particles of masses m_(1) and m_(2) initially at rest start moving towards each other under their mutual force of attraction. The speed of the centre of mass at any time t, when they are at a distance r apart, is

When two blocks connected by a spring move towards each other under mutual interaction,

Two particles of masses 1kg and 2kg are placed at a distance of 50cm . Find the initial acceleration of the first particle due to gravitational force.

When two blocks connected by a spring move towards each other under mutual interaction

Two particles A and B with particle A having mass m, are moving towards each other under their mutual force of attraction. If their speeds at certain instant are v and 2v respectively, then find the K.E. of the system.

Two point masses of mass 4m and m respectively separated by d distance are revolving under mutual force of attraction. Ration of their kinetic energies will be:

Two point masses of mass 4m and m respectively separated by d distance are revolving under mutual force of attraction. Ratio of their kinetic energies will be

Consider a system of two particles of masses m_(1) and m_(2) separated by a distance r. Suppose they start to move towards each other due to their mutual attraction (attractive force may be electrical, gravitational, etc.).
