Question:

Given below are two statements

Statement I : magnetic field does zero work on a charge particle entering with uniform velocity.

Statement II : A charge particle entering a region of uniform magnetic field with its velocity perpendicular to the direction of magnetic field, executes a circular motion.

In the light of the above statement, choose the most appropriate answer from the options given below

Options:

Both statement I and statement II are correct

Both statement I and statement II are incorrect

Statement I is correct but statement II is incorrect

Statement I is incorrect but statement II is correct

Correct Answer:

Both statement I and statement II are correct

Explanation:

The correct answer is option (1) : Both statement I and statement II are correct

The work done by magnetic field is zero on a charge particle entering with uniform velocity as displacement of particle is perpendicular to magnetic force. A charge particle entering a region of uniform magnetic field with its velocity perpendicular to direction of magnetic field executes a circular motion.
