Question

If quantity of the charge on each of the two bodies is doubled, the force between them becomes
A. Twice
B. Four times
C. Nine times
D. Sixteen times

Answer 1

Explanation:

If the distance between the two charges is doubled, the force F will be reduced to one-fourth of F.

Answer 2

Answer:

four times

Explanation:

it says *charge in each body is doubled* means

Q1=2 and q2=2

force is directly proportional to charge therefore

by using formula F=K q1 x q2 / r²

considering only the relation of F and q

we can say if charge becomes 4 then force will also be 4F

in short 2 times increase on each charge means total 4 times increase which results 4time increase in force
