Two bar magnets of the same length, breadth and mass and having the magnetic dipole moment 3M and 2M are allowed to oscillate in the vibration magnetometer. First we put the two magnets with their north pole pointing in the same direction and then pointing in opposite direction. If the time period in the first case is T, then the time period in the second case will be
- \(\sqrt{5} T\)
- \(\sqrt{3} T\)
- \(\sqrt{2} T\)
- T
Answer
(A) 5 T
