Question

If one of two interacting charges is doubled, the force between the charges will _____________.

Answer 1

If one of two interacting charges is doubled, the force between the charges will double.

Step-by-step explanation:

The force between two charges is given by Coulomb's law

`F=(k q1 q2)/(r^(2))`

K=constant= 9 x 10⁹ N m²/C²

q1= charge on first particle

q2= charge on second particle

r= distance between the two charges

Now if the first charge is doubled,

we get
`F'=(k (2q1) q2)/(r^(2))`

F'= 2 F

Thus the force gets doubled.
