If charge of one object is doubled then the electromagnetic force is (F = k*q1*q2 / r^2)

• doubled

• half

• 4 times as big

• 1/4 times as big

If the distance between two charges is doubled then the electromagnetic force is (F = k*q1*q2 / r^2)

• doubled

• half

• 4 times as big

• 1/4 times as big
