Electrically neutral objects cannot exert an electrical force on each other, but they can exert a gravitational force on each other. electrically neutral objects cannot exert an electrical force on each other, but they can exert a gravitational force on each other. a. true b. false

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.
