Question

Among the following statements the one which is false in case of a particle moving along a circular path
with a constant angular velocity
[ ]
a) The velocity vector is tangential to the circle
b) The acceleration vector is tangential to the circle
c) The acceleration vector is always towards the center of circle
d) The velocity and acceleration vectors are perpendicular to each other.​

Answer 1

Answer:

b

Explanation:

A particle moving in a circle with a constant angular speed has centripetal acceleration only and zero tangential acceleration.

As v=rw

w= constant ⟹v= constant , thus a

v

=0

Also centripetal acceleration, a

c

=rw

2

towards centre.
