Two point charges are placed at a certain distance apart. How will the force change if the distance between them was reduced to one fourth its original value, while the charge was increased two times?

What is relative velocity? in which condition is relative velocity known by adding the velocity of the first body and that of the second body

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
