Why do objects accelerate when dropped on earth?

a) the force of earth's gravity continuously acts on the object making it go faster
over time.

b) objects in motion always accelerate.

c) for every action, there is an equal and opposite reaction.

d) air pressure increases near the ground.

Answer the above statement is ( false );

The answer is 4f======since electrostatic force is given by    we let f be the electrostatic force when  r = 1 m    if we let  denote the electrostatic force when the distance is decreased so that r = 0.5m, then    we established earlier that f = kq₁q₂. therefore    the force will now be 4f.
