A) ? 2F
B) F/3
C) 2F/3
D) ? F/3
Correct Answer: C
Solution :
\[F\propto \frac{{{i}_{1}}{{i}_{2}}}{a}\]; Since one of the current increase two times and distance increases three times, so force become \[\frac{2}{3}\]times. Also due to the reversal of direction of current force becomes negative.You need to login to perform this action.
