14 cm length of wire carries a current of 1.5 A in the positive z direction. The force on this wire due to a magnetic field is = (-0.2 + 0.2 ) N. If this wire is rotated so that the current flows in the positive x direction, the force on the wire is = 0.2 N. Find the magnetic field

Explanation:

We are given that

Length of wire,L=14 cm=

1 m=100 cm

Current,I=1.5 k A

Magnetic force,F=(-0.2i+0.2 J)N

Magnetic force,F=

By comparing on both sides

When the current flows in positive x direction

Then,

By comparing on both sides we get

Magnetic field,

your answer is c! hope this : )
