A long straight wire is carrying current `I_(1)=2//5A` in `+z` direction. The x-y plane contains a closed circular loop carrying current `l_(2)=5//2 A` and not encircling the straight wire, then the force (in newton) on the loop will be ? (radius of the circular loop `R=3//4 m`).

Explanation

The force on current elements 1 and 2 is equal in magnitude and opposite in direction
`rArr F_("net")=0`
