Question

A conductor in the form of a right angle ABC with AB = 3cm and BC = 4 cm carries a current of 10 A. There is a uniform magnetic field of 5T perpendicular to the plane of the conductor. The force on the conductor will be 

(a) 1.5 N 

(b) 2.0 N 

(c) 2.5 N 

(d) 3.5 N

Answer 1

Correct option (c) 2.5 N

Explanation: 

According to the question figure can be drawn as shown below. 

Force on the conductor ABC = Force on the conductor AC
