In  a forced damped oscillator ,maximum phase difference between sinusoidal driving force and damping oscillator is ∏ . why ?. can't be it more than ∏ ?

This sounds like a homework question, so I will point you in this direction:
If you have a driving force the motion of the 'driven' must lag behind the motion of the driver. What would happen if the phase lag went beyond antiphase, 180, ∏?

Angles here are measured in radians. There are 2π radians in a complete cycle.

In the steady state, with driver and load in synchronisation, the phase difference cannot exceed the range π.

Think what it means if the "driver" lags behind the "load"...
