Answer:
Angular acceleration,
Explanation:
It is given that,
Mass of the solid sphere, m = 245 g = 0.245 kg
Diameter of the sphere, d = 4.3 cm = 0.043 m
Radius, r = 0.0215 m
Force acting at a point, F = 0.02 N
Let is its angular acceleration. The relation between the angular acceleration and the torque is given by :
I is the moment of inertia of the solid sphere
For a solid sphere,
So, its angular acceleration is . Hence, this is the required solution.
