Question

A wire is bent in the form of an equilateral triangle of side 100 cm and carries a current of 2 A. It is placed in a magnetic field of induction 2.0 T directed perpendicular into the plane of paper. The direction and magnitude of magnetic force asting on each side of the triangle will be (A) 2 N, normal to the side towards centre of the triangle (B) 2 N, normal to the side away from the centre of the triangle (C) 4 N, normal to the side towards centre of the triangle (D) 4 N, normal to the side away from the centre of the triangle

Q. A wire is bent in the form of an equilateral triangle of side $100 c m$ and carries a current of $2 A$ . It is placed in a magnetic field of induction $2.0 T$ directed perpendicular into the plane of paper. The direction and magnitude of magnetic force asting on each side of the triangle will be

2 N, normal to the side towards centre of the triangle

2 N, normal to the side away from the centre of the triangle

4 N, normal to the side towards centre of the triangle

4 N, normal to the side away from the centre of the triangle

$F = i (i \times B)$
$= 2 (1) (2)$
$= 4 N$
Nomal to side towards centre of triangle.
