Question

A particle is going in a spiral path as shown in Fig. with constant speed. Then :

• A. its velocity is constant
• B. its acceleration is constant
• C. magnitude of its acceleration is constant
• D. The magnitude of acceleration decreases continuously

Answer 1

The correct option is C magnitude of its acceleration is constant

When an object follows curved path, its magnitude of linear velocity i.e. speed will not change but direction of linear velocity will change continuously. Hence, the acceleration of an object will change but its magnitude will remain constant in any direction.
