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.
I haven´t learned that yet I´m sorry.
The liquid state must be supplied with the most energy.
