Question

A conductor in the fom1 of a right angle `\triangle` ABC with AB = 3 cm and BC = 4 cm carries a current of 15 A. There is a uniform magnetic field of 8 T perpendicular to the plane of the conductor. The force on the conductor will be ______.

विकल्प

• 1.5 N

• 6.0 N

• 2.5 N

• 3.5 N

Answer 1

A conductor in the fom1 of a right angle `\triangle` ABC with AB = 3 cm and BC = 4 cm carries a current of 15 A. There is a uniform magnetic field of 8 T perpendicular to the plane of the conductor. The force on the conductor will be 6.0 N.

Explanation:

Force on the conductor ABC = Force on the conductor AC

F = I/B sin `theta`

F = I/B` ...(because theta = 90°)`

`because` F = 15 x ( 5 x 10^-2 ) `xx` 8 = 6 N
