Question

A very long straight wire carrying a current i is kept parallel to a very long non- conducting straight wire of uniform charge per unit length $\lambda$. Both the wires are now given longitudinal parallel velocities $V_1$ and $V_2$ with respect to ground observer. The force per unit length on the non - conducting charged wire as recorded by the ground observer is dependent on

• A. $V_1$
• B. $V_2$
• C. d
• D. i

Answer 1

Answer: (B), (C), (D)

The correct options are
B

$V_2$

C

d

D

i

The force per unit length depends on the distance of separation, current in the wire (produced due to its motion)
