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:
The pressure is 
Explanation:
From the question we are told that
The volume of the container is 
The mass of
is
The root-mean-square velocity is 
The root -mean square velocity is mathematically represented as

Now the ideal gas law is mathematically represented as

=> 
Where n is the number of moles which is mathematically represented as

Where M is the molar mass of
So

=> 
=> 
=> 
substituting values
=> 
=>
