@All.
No way for it becomes zero because the shear force reaches zero at the point l/root 3 from the fixed end.

Maximum SF will be wl/4.
Centre is point of inflection, where SF changes sign, so its Zero.

The parabolic nature causes the SF to be zero at centre.
@Sri, your answer corresponds to point load at centre.
