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.).

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

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

Two bodies initially at rest, started moving towards each other due to mutual attraction. Which of the following is incorrect ?

Two particles of mass m_(1) and m_(2) , approach each other due to their mutual gravitational attraction only. Then

Two objects of masses m and 4m are at rest at an infinite separation. They move towards each other under mutual gravitational attraction. If G is the universal gravitaitonal constant, then at separation r

Two bodies of masses m_(1) and m_(2) are initially at infinite distance at rest. Let they start moving towards each other due to gravitational attraction. Calculate the (i) ratio of accelerations and (ii) speeds at the point where separation between them becomes r.

Two objectes of mass m and 4m are at rest at and infinite seperation. They move towards each other under mutual gravitational attraction. If G is the universal gravitational constant. Then at seperation r

Two masses m_(1) and m_(2) (m_(1) lt m_(2)) are released from rest from a finite distance. They start under their mutual gravitational attraction
