Two particles A and B of masses 1 kg and 2 kg respectively are kept 1 m apart and are released to move under mutual attraction. Find The speed A when that of B is 3.6 cm/hor. What is the separation between the particles at this instant?

Two particles A and B of masses 1kg and 2kg , respectively, are kept at a very large separation. When they are released, they move under their gravitational attraction. Find the speed (in 10^(-5) m//s ) of A when that of B is 3.6 cm//hr .

Two particles P and Q of mass 1 kg and 3 kg respectively start moving towards each other form rest under mutual attraction. What is the velocity of their center of mass ?

Two particles P and Q of masses 2 kg and 4 kg initially at a distance of 2m from each other are released. If the particles move under mutual attraction, then find speed of particles P when speed of Q is 5 cm/hour. Also find the separation between these particles at this instant.

Two particles A and B of mass 1 kg and 4 kg respectively approach each other due to their mutual gravitational force only. Then the ratio of acceleration of A to B at any instant is

Two particles A and B of mass 1 kg and 4 kg respectively approach each other due to their mutual gravitational force only. Then the ratio of acceleration of A to B at any instant is

Two small bodies of masses 10 kg and 20 kg are kept a distnce 1.0 m apart and released. Assuming that only mutual gravitational force are acting, find the speeds of the particles when the separation decreases to 0.5 m.
