Question

A cell is connected between the points A and C of a circular conductor ABCD of centre O with angle A $O C equals 6 0 to the power of o end exponent$ ^.If $B subscript 1 end subscript$ and $B subscript 2 end subscript$ are the magnitudes of the magnetic fields at O due to the currents in ABC and ADC respectively, the ratio $fraction numerator B subscript 1 end subscript over denominator B subscript 2 end subscript end fraction$ is

0.2
6
1
5

The correct answer is: 1

$B equals fraction numerator mu subscript 0 end subscript over denominator 4 pi end fraction fraction numerator theta i over denominator r end fraction rightwards double arrow B proportional to theta i$ (but $fraction numerator i subscript 1 end subscript over denominator i subscript 2 end subscript end fraction equals fraction numerator l subscript 2 end subscript over denominator l subscript 1 end subscript end fraction equals fraction numerator theta subscript 2 end subscript over denominator theta subscript 1 end subscript end fraction$ )

$rightwards double arrow fraction numerator B subscript 1 end subscript over denominator B subscript 2 end subscript end fraction equals fraction numerator theta subscript 1 end subscript over denominator theta subscript 2 end subscript end fraction. fraction numerator i subscript 1 end subscript over denominator i subscript 2 end subscript end fraction$
So, $fraction numerator B subscript 1 end subscript over denominator B subscript 2 end subscript end fraction equals fraction numerator theta subscript 1 end subscript over denominator theta subscript 2 end subscript end fraction cross times fraction numerator theta subscript 2 end subscript over denominator theta subscript 1 end subscript end fraction$
$rightwards double arrow B subscript 1 end subscript equals B subscript 2 end subscript$
