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 the figure) due to the magnetic field of wire 1 ?

A

`(mu_(0))/(2pir)i_(1)i_(2)dltantheta`

B

`(mu_(0))/(2pir)i_(1)i_(2)dlsintheta`

C

`(mu_(0))/(2pir)i_(1)i_(2)dlcostheta`

D

`(mu_(0))/(4pir)i_(1)i_(2)dlsintheta`
