Question

As shown, the two charges are 3 cm apart. What will happen to this force if the distance between the charges is doubled? Use proportional reasoning to find the answer and then check by moving the charges.​

Answer 1

Answer:

if the distance between the two charges is doubled, the attraction or repulsion becomes weaker, decreasing to one-fourth of the original value. If the charges come 10 times closer, the size of the force increases by a factor of 100. The size of the force is proportional to the value of each charge.
