Answer 1

Explanation :

(5) When the object is moving in a circular path, it is said to possess uniform circular motion. The acceleration of the object in uniform circular motion is called centripetal acceleration. Its direction is towards the circle.

The velocity of an object in this case is tangential to the circle and is always changing.

The mathematical expression for centripetal acceleration is :

$a_c=\dfrac{mv^2}{r}$

v is the velocity of object

r is the radius of circle.

So, the centripetal acceleration is inversely proportional to radius of circular path.

Hence, the correct option is (B) '' larger in magnitude the smaller the radius of circle ''.
