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
2.5 N
Explanation
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
