Magnetic Effects of Current and Magnetism Part 2

Two circular coils P and Q of 100 turns each have same radius of π‌cm. The currents in P and R are 1A and 2 A respectively. P and Q are placed with their planes mutually perpendicular with their centers coincide. The resultant magnetic field induction at the center of the coils is √x‌mT, where x=____ [.
