A block of mass m rigidly attached with a spring of spring constant K, is compressed through a small distance A. If the block is now released, the time taken by the block is going from P to Q will be
1
\(\frac{3}{{4\pi }}\sqrt {\frac{m}{K}} \)
2
\(\frac{4\pi}{{ 3}}\sqrt {\frac{m}{K}} \)
3
\(\frac{3\pi}{{ 4}}\sqrt {\frac{m}{K}} \)
4
\(\frac{3\pi}{{ 4}}\sqrt {\frac{K}{m}}\)
