1.A bar magnet is oscillating in the Earth's magnetic field with a period TTT. What happens to its period and motion if its mass is quadrupled?a.motion remains simple harmonic with time period =T/2= T/2=T/2b.motion remains S.H.M with time period =2T= 2T=2Tc.motion remains S.H.M. with time period =4T= 4T=4Td.motion remains S.H.M and period nearly constantLogin to continueOnly logged in users canattempt or see the solution.
