Wires 1 and 2 carrying currents 
and 
respectively are inclined at an angle 
to each other. What is the force on a small element dl of wire 2 at a distance of r from 1 (as shown in figure) due to the magnetic field of wire 1
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Length of the component dl which is parallel to wire (1) is dl cos θ θ , so force on it
.
