The two types of acceleration

Question

Statement -A : The net acceleration of a particle in circular motion is always along the radius of the circle towards the centre
Statement -B : The velocity vector of a particle at a point is always along the tangent to the path of the particle at that point

Moderate

A

A only true
B

B only true
C

Both A & B are true
D

Both A & B are false

Solution

In case of uniform circular motion only , acceleration of the particle is directed towards the centre of circular path.In case of non-uniform circular motion , tangential acceleration is not zero and as a result resultant acceleration is not radially inward. So statement A is not a general statement Velocity always lies along the tangent drawn to the circular path at the location of the particle, So statement B is true.
