Two particles of masses `m_(1)` and `m_(2)` are initially at rest infinite distance apart. If they approach each other under inverse square law of force `(F=k//r^(2))` find their speed of approach at the instant when they are distance d apart.

Two particles of masses m_(1) and m_(2) are intially at rest at an infinite distance apart. If they approach each other under their mutual interaction given by F=-(K)/(r^(2)) . Their speed of approach at the instant when they are at a distance d apart is

Two bodies of masses m_1 and m_2 are initially at rest and infinite distance apart. Due to mutual attraction, they approach each other. When they are r distance apart, their relative velocity of approach is

Two particles of masses m and M are initially at rest at an infinite distance apart. They move towards each other and gain speeds due to gravitational attraction. Find their speeds when the separation between the masses becomes equal to d.

Two particles of masses m and M are initially at rest at an infinite distance part. They move towards each other and gain speeds due to gravitational attracton. Find their speeds when the separation between the masses becomes equal to d .

Two bodies of masses m_1 and m_2 initially at rest at infinite distance apart move towards each other under gravitational force of attraction. Their relative velocity of approach when they are separated by a distance r is (G= universal gravitational constant.)
