What happens to the force between two charged objects if you reduce the distance between two objects from 30 cm to 10 cm?
A
1/3X
B
20X
C
3X
D
9X
Explanation: 

Detailed explanation-1: -The size of the force varies inversely as the square of the distance between the two charges. Therefore, if the distance between the two charges is doubled, the attraction or repulsion becomes weaker, decreasing to one-fourth of the original value.

Detailed explanation-2: -The electric force between objects is inversely proportional to the distance squared, so as the distance increases, the force decreases and vice versa-as the distance decreases, the force increases.

Detailed explanation-3: -Answer: If the distance between them is change to 5 times of before then new force will be 1 25 times of before. Explanation: The Coulomb force between two charge is inversely proportional with the distance between them.

Detailed explanation-4: -Hence, when the distance between the objects is reduced to half, the gravitational force increases four times.
