Two waves are propagating to the point *P* along a straight line produced by two sources, *A* and *B,* of simple harmonic and equal frequency. The amplitude of every wave at *P* is ‘*a*’ and the phase of *A* is ahead by π/3 than that of *B,* and the distance *AP* is greater than *BP* by 50 *cm*. If the wavelength is 1 *meter, t*hen the resultant amplitude at point *P* will be:
