Two masses m1 and m2(m1<m2) are released from rest from a finite distance. They start under their mutual gravitational attraction.
Two massesm1 and m2 (m1 < m2) are released from rest from a finite distance. They start under their mutual gravitational attraction-
Two spheres of masses m1 and m2 (m1>m2) respectively are tied to the ends of a light, inextensible string which passes over a light frictionless pulley. When the masses are released from their initial state of rest, the acceleration of their centre of mass is:
