Force and Torque on a Current Carrying Conductor
question_answer
A conductor in the form of a right angle ABC with AB = 3 cm and BC = 4 cm carries a current of 10 A. There is a uniform magnetic field of 5 T perpendicular to the plane of the conductor. The force on the conductor will be [MP PMT 1997]
A) 1.5 N
B) 2.0 N
C) 2.5 N
D) 3.5 N
Correct Answer:
C
Solution :
According to the question figure can be drawn as shown below. Force on the conductor ABC = Force on the conductor AC = 5 ´ 10 ´ (5 ´ 10?2) = 2.5 N
