Question

Assertion: The circular motion is accelerated even though the speed of the body is uniform.

Reason: Due to continuous change in the direction of motion, the motion is no longer uniform, i.e., the motion is an accelerated motion.

Options

• If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

• If both Assertion and Reason are true, but Reason is not correct explanation of the Assertion.

• If Assertion is true, but the Reason is false.

• If Assertion is false, but the Reason is true.

Answer 1

If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

Explanation:

In circular motion, even if the speed of the body remains constant, its velocity changes continuously because the direction of motion keeps changing. Therefore, the Assertion (A) is true.

A continuous change in the direction of velocity means that the body has acceleration. Therefore, the Reason (R) is true and correctly explains the Assertion.

Hence, both A and R are true and R is the correct explanation of A.
