Let BP and BQ be the magnetic field produced by the wire P and Q which are placed symmetrically in a rectangular loop ABCD as shown in figure. Current in wire P is I directed inward and in Q is 21 directed outwards. If tesla meter, tesla meter & tesla meter the value of I will be:
(A) 8 A (B) 4 A (C) 5 A (D) 6 A
