The correct answer is
A) true
In fact, the electrical force can be present only if the two objects have a net charge different from zero, because the electrical force is proportional to the value of the charges:
so, if they are neutral they cannot exert an electrical force between each other, because their charge Q is zero.
Viceversa, the gravitational force is always present when the objects have masses, since the force is proportional to the value of the masses:
so, even if the two objetcs are neutral, if they have mass, they exert a gravitational force to each other.

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 ,
