Two particles of equal mass m go around a circle of radius R under the influence of their mutual gravitational attraction.the speed of each particle with respect to their center of mass will be?? Ans) The Speed will be equal to their velocities in inertial frame itself as there centre of mass will be stationary.

Q. Write down Schrodinger's wave equation for a particle in a three dimensional box. Solve it to get eigen functions and show that the eigen values are discrete. Ans. Fr
With respect to the center of mass the speed of each particle is (Gm/4R)1/2 as their is no external force acting on the system so velocity of the center of mass is zero velocity of each particle is (Gm/4R)1/2.
