AIPMT MAIN 2008 Physics Magnetic Force on Current Loop MCQ Question
Type: MCQ-conceptual-Medium-Class 12
A closed loop PQRS carrying a current is placed in a uniform magnetic field. If the magnetic forces on segments PS, SR and RQ are F₁, F₂ and F₃ respectively and are in the plane of the paper and along the directions shown, the force on the segment QP is
A
F₃ - F₁ + F₂
B
F₃ - F₁ - F₂
C
(F₃ - F₁)^²⁺ F₂^2
D
(F₃ - F₁)^²⁻ F₂^2
Correct Answer
Option C
Detailed Explanation
Since net force on current carrying loop in uniform magnetic field is zero therefore force on remaining segment will be equal and opposite to F.
