Question

The electrical force between two objects 36N. If the distance between the two objects is doubled the force between them will be

Answer 1

The electrical force is 9N

Step-by-step explanation:

For point loads, charged bodies very small compared to the distance r that separates them, Coulomb discovered that the electric force is proportional to
`(1)/(r^(2))`. So, if the distance is doubled, the force will decrease a
`(1)/(4)` of its initial value.

`F=(36N)/(4)=9N`
