Question

A particle is describing a uniform circular motion with a certain constant speed. The INCORRECT statement is

• A. The velocity and acceleration vectors are perpendicular to each other
• B. The velocity vector is tangential to the circular path
• C. The centripetal acceleration is a variable acceleration
• D. The acceleration vector points to the centre of the circle
• E. The acceleration vector is tangential to the circular path

Hint:

In uniform circular motion, acceleration always acts towards the center, while velocity is tangential.

Answer 1

Answer: (E)

Step 1: In uniform circular motion, acceleration is always directed towards the center (centripetal acceleration). 
Step 2: The velocity is always tangential to the circular path, meaning it is perpendicular to the acceleration vector. 
Step 3: Since centripetal acceleration points to the center, it is not tangential to the path. 
The incorrect statement is (E).
