Answer :
The centripetal acceleration of the particle is found to be 16.9m/s².
When a body moves in a circular motion it poses some centripetal acceleration.
This centripetal acceleration is given by
A = v²/r
Where A is the centripetal acceleration,
v is the uniform speed and,
r is the radius of the circle in which the particle is moving.
The uniform speed is given to be 1.3m/s. and radius of the circle is 10 cm.
Converting centimetre into metre,
The radius of the circle is 0.1m.
Now, putting all the values,
a = 1.3 × 1.3/0.1
a = 16.9 m/s².
So, the centripetal acceleration of the particle is 16.9m/s².
