Question

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

• A. $1.5N$
• B. $2.0N$
• C. $2.5N$
• D. $3.5N$

Answer 1

The correct option is C $2.5N$

$F=Bil=5\times 10\times 5\times {10}^{-2}N=2.5N$
