QAIPMT-2007-Ch-2285: NEET 2008 Physics - Class 12 AIPMT-2007-Ch-2285 Solution: A closed loop PQRS carrying a current is placed in a uniform…

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

F_1

F_2

and

F_3

respectively and are in the plane of the paper and along the directions shown, the force on the segment QP is

Multiple Choice Options

A $\sqrt{(F_3-F_1)^2-F_2^2}$
B $F_3-F_1+F_2$
C $F_3-F_1-F_2$
D $\sqrt{(F_3-F_1)^2+F_2^2}$

Step-by-Step Verified Solution

According to the figure the magnitude of force on the segment QM is F 3 � F 1 and PM is F 2 . Therefore, the magnitude of the force on segment PQ is ( F 3 _ F 1 ) 2 + F 2 2
