Two perpendicular circular loops of radius `'a'` and `'b'` carry currents `i_(1)` and `i_(2)` respectively. The loop of radius `'b'` is `xy` plane and centered at `(b,0,0)`. The loop of radius `'a'` is in `yz` plane centred at `(0,0,0)`. The magnitude field at centre `(b,0,0)` is

Options

B. `(mu_(0))/2[(i_(1)b^(2))/((a^(2)+b^(2))^(3//2))hati+(i_(2))/bhatk]`
C. `(mu_(0))/2[(i_(1)a^(2))/((a^(2)+b^(2))^(3//2))hati-(i_(2))/bhatk]`
D. none of these
