Two magnets with the same dimensions and mass, but of magnetic moments `mu_1 =100Am^2`and `mu_2= 50 Am^2`are jointly suspended in the earth's magneticfield. So as to perform angular oscillations in a horizontal plane.When their like poles are joinedtogether the period of their angular S.H.M is 5s. Find the period of angular S.H.M, when theirunlike poles are joined together.
