12th Physics: Moving Charges and Magnetism

1 / 10

1. An electron having a charge e moves with a velocity v in X-direction. An electric field acts on it in Y-direction? The force on the electron acts in

positive direction of Y-axis

negative direction of Y-axis

positive direction of Z-axis

negative direction of Z-axis

2 / 10

2. A charged particle moves through a magnetic field in a direction perpendicular to it. Then the

velocity remains unchanged

speed of the particle remains unchanged

direction of the particle remains unchanged

acceleration remains unchanged

3 / 10

3. Choose the correct option
Assertion : Free electrons always keep on moving in a conductor even then no magnetic force act on them in magnetic field unless a current is passed through it.
Reason : The average velocity of free electron is zero.

Assertion is correct, reason is correct; reason is a correct explanation for assertion.

Assertion is correct, reason is correct; reason is not a correct explanation for assertion

Assertion is correct, reason is incorrect

Assertion is incorrect, reason is correct.

cylindrical symmetry

cubical symmetry

unsymmetrical

6 / 10

6. A current carrying circular loop of radius R is placed in the x-y plane with centre at the origin. Half of the loop with x > 0 is now bent so that it now lies in the y-z plane.

The magnitude of magnetic moment now diminishes

The magnetic moment does not change

The magnitude of B at (0, 0, z), z > R increases

The magnitude of B at (0, 0, z), z >> R is unchanged

7 / 10
