Question

A wire abc is carrying current I. It is bent as shown in the figure and is placed in a uniform magnetic field B. Length ab = l and $∠ a b c = 45^{\circ}$ . What is the ratio of force on bc to that on ab?

Options:

A .

\sqrt{2}

B .

\frac{1}{\sqrt{2}}

C .

1

D .

\frac{3}{2}

Answer: Option C
:
C

\frac{F_{1}}{F_{2}} = \frac{B i l_{1} c o s 45}{B i l l s i n 90^{\circ}} \frac{F_{1}}{F_{2}} = 1
