Multiple choice

Directions: There are two statements, one labeled the Assertion (A) and the other labeled the Reason (R). Examine the statements and decide if the Assertion A and Reason R are individually true and if so, whether the reason is the correct explanation of the assertion. Select your answers to the question from the codes given below:

Assertion (A): A particle moving in a uniform circular motion has uniform velocity. Reason (R): The particle has a uniform speed.

  1. Both A and R are true and R is the correct explanation of A.

  2. Both A and R are true and R is not the correct explanation of A.

  3. A is true but R is false.

  4. A is false but R is true

D Correct answer
Explanation

Assertion A is false because velocity is a vector; in circular motion, the direction changes constantly, so velocity is not uniform. Reason R is true because the speed (magnitude of velocity) remains constant.
