The position of point from wire where net magnetic field is zero, due to following current distribution, will be
1 at a point lying outside the wires
2 at a point lying between the wires
3 at a point lying between the wires
4 at a point lying outside the wires
Explanation:
For to be zero at , Thus will be zero at point at a distance from wire carrying current.
