Question

Q1= Four Particles of equal masses M move along a circle
of radius R under the action of their mutual gravitational
attraction Find the speed of each particle

nitish.gupta · Accepted Answer

Since the mass of the particles are same and they are moving
under the same circumstances therefore the particles will always
remain diametrically opposite so that the force on each particle
will be directed along the radius, so we can consider the circular
motion of one such particle and calculate the speed of it from the
centripetal force concept and that will be exactly same for every
other particle too
