Physics Moving Charge and Magnetism Matching Type Question MCQ (Single Correct)

Consider a closed loop in the form of a trapezium carrying current I. Match the following regarding the magnitude of magnetic field at point P.

Column-I	Column-II
(A)	Magnetic field due to AB	(I)	is greater than that due to DA
(B)	Magnetic field due to BC	(II)	is greater than that due to CD
(C)	Magnetic field due to DA	(III)	is not equal to zero
(D)	Magnetic field due to complete figure	(IV)	is zero

-(I,IV) -(IV) -(I,II) -(IV)

-(II) -(I,II,III) -(II) -(I,II,III)

-(I,II) -(IV,II) -(I,II) -(II,III)

-(I,II,III) -(I,II) -(II) -(I,II,III)

Text Solution

Verified by Experts

The correct answer is:

At P , magnetic field due to AB and CD will be zero.

Net field at P :

Hence, we can find the answers given below.
(II) speed remain the same inside the dees because of the magnetic field but direction undergoes change continuously.
