Question

The angle between centripetal acceleration and tangential acceleration is.

• A. \(180^\circ\)
• B. \(0^\circ\)
• C. \(90^\circ\)
• D. \(45^\circ\)

Hint:

Remember — in circular motion, centripetal acceleration points radially inward and tangential acceleration is along the tangent, making them perpendicular (\(90^\circ\)) to each other.

Answer 1

The Correct Option is C

In circular motion, centripetal acceleration always acts towards the center of the circle, while tangential acceleration acts along the tangent to the path at any instant.
Since these two directions are mutually perpendicular, the angle between centripetal and tangential acceleration is \(90^\circ\).
