The figure shows tow coaxial circulalr loop a1 and 2, which forms same solid angle `theta` at point `O`. If `B_1` and `B_2` are the magnetic fields produced at the point `O` due to loop 1 and 2 respectively, then

A straight wire and a circular loop both carrying currents are in the same vertical plane. There is no contact between the two at the point A. If B_(1) and B_(2) are magnetic fields due to i_(1)andi_(2) respectively at the point C, the centre of the loop, then the total field at C is:
