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,

the higher the current the higher the mag field around it the higher the influence on the compass

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
