Wires `1 and 2` carrying currents `i_(1) and i_(2)` respectively are inclined at an angle `theta ` to each other. What is the force on a small element `dl` of wire `2` at a distance of `r` from wire 1 ( as shown in figure) due to the magnetic field of wire 1`?

Options

A. `(mu_(0))/(2pir) i_(1) i_(2) dl tan theta`
B. `(mu_(0))/(2pir) i_(1) i_(2) dl sin theta`
C. `(mu_(0))/(2pir) i_(1) i_(2) dl cos theta`
D. `(mu_(0))/(4pir) i_(1) i_(2) dl sin theta`

Answer

C
