A beaker containing an ideal fluid executes plane `SHM` in a horizontal plane according to the equation `x=(sqrt(3)g)/(omega^(2))sinomegat`, `O` being the mean position. A bob is suspended at `S` through a string of length `L` as shown in the figure. The line `SO` is vertical. Assuming `L gt gt (sqrt(3)g)/(omega^(2))`.
The tension in the string is maximum at time `t=`

Options

A. `pi//2omega`
B. `pi//omega`
C. `pi//4omega`
D. none of these

Explanation

Tension is maximum at the mean position.
