The electrostatic force between two charged objects is given by
where
k is the Coulomb's constant
q1 is the charge of the first object
q2 is the charge of the second object
r is the separation between the two objects
In our problem:
So if we plug these numbers into the equation, we can find the electrostatic force between the two objects:

Answer:
Explanation:
We are given that
Net force=F=
Mass,m=1.21 kg
Radius,r=0.723 m
We have to find the magnitude of its angular acceleration.
Moment of inertia ,
Substitute the values
Torque ,
