A current loop PQRS is held fixed on the plane of the paper as shown in the figure The QR radius 2a and SP radius a of the loop are joined by two straight wire PQ and RS A steady current is flowing in the loop Angle made by PQ and RS at the origin is 60 160 2a R Due to the presence of the current and the net magnetic force per unit
