Two solenoids acting as short bar magnets P and Q are arranged such that their centres are on the X-axis and are separated by   a large distance . The magnetic axes of P and Q are along X and Y-axes, respectively. At a point R, midway between their centres , if B is the magnitude of induction due to Q , then the magnitude of total induction at R due to the both magnets is
