The length of a magnet is large compared to its width and breadth. The time period of its oscillation in a vibration magnetometer is 2 s. The magnet is cut along its length into three equal parts and then placed on each other with their like poles together. The time period of this combination will be
- 2 s
- \(\frac{2}{3} 5\)
- \(2 \sqrt{35}\)
- \(\frac{2}{\sqrt{3}} 5\)
Answer
(A) 2 s
