AIPMT PRELIMS 2011 Physics Magnetic Force on Current-Carrying Conductors MCQ Question

Type: MCQ-conceptual-Medium-Class 12

A right angle isosceles triangle ABC is placed in a uniform magnetic field acting along AB. If the magnetic force on the arm BC is F\vec{F}, the force on the arm AC is

Question diagram
A

√2 F\vec{F}

B

−√2 F\vec{F}

C

F\vec{F}

D

F\vec{F}

Correct Answer

Option C

Detailed Explanation

The force on AC is opposite to the force on BC due to the direction of the magnetic field and the geometry of the triangle. Hence, it is −F\vec{F}.
