Two long parallel wires are $30 c m$ apart carrying currents $10 A$ and $15 A$ respectively in the same direction. The force acting over a length of $5 m$ of the wires is

Options:

Answer:

Solution:

Force acting between two parallel wire

$F = \frac{μ_{0} i_{1} i_{2}}{2 π r} l$

$F = \frac{(2 \times 1 0^{- 7}) (10) (15)}{0.3} \times 5$

$F = 5 \times 1 0^{- 4} N$
