Question

In a circular motion of a stone tied to a string, ___

• A. centripetal and tangential acceleration both are present
• B. only centripetal acceleration is present
• C. only tangential acceleration is present
• D. only centripetal force

Answer 1

The correct option is A

centripetal and tangential acceleration both are present

In a circular motion of an object, both tangential and centripetal or center-seeking acceleration play an important role. Tangential acceleration comes into the picture because of tangential velocity. Centripetal acceleration plays an important role to keep the object in the stable circular orbit or loop.
