NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Two negative charges, each of magnitude 21 x 10- C, are located at a distance of 12 cm from each other. What is the magnitude of the force exerted on each charge? Take the value of Coulomb's constant as 9 x 109 N.m2/C2. (You must provide an answer before moving on to the next part.) The magnitude of the force exerted on each charge is N.Two charged particles exert an electrostatic force of 30 N on each other. What will the magnitude of the force be if the distance between the two particles is increased to twice the original distance? The magnitude of the electrostatic force 151:\
