Q1.)2 massive particles of masses M and m (M>m) are seperated by a distance r. They rotate with equal angular velocity under their gravitational attraction. What is the linear speed of the particle of mass m?Q2.)4 particles of equal mass M move along a radius R under the action of their mutual gravitational attraction. Find the speed of each particle?
