Two charges are separated by a certain distance. If the magnitude of one charge only is doubled, the force on each charge is a. halved.
b. doubled.
c. tripled.
d. quadrupled.

this would be about 43%

explanation:

to push or pull an object in a certain direction is known as force. a force in moving an object from one place to another.

force depends on the mass of an object. so, more is the mass of an object more will be the force required to move the object.

thus, we can conclude that the use of force to move an object is push or pull.
