Question

How would the force between two charged particles change if one of the charges were to triple in strength (3x stronger)?

A. 9x stronger

B. 1/3 as strong

C. 1/9 as strong

D. 3x stronger

Answer 1

The correct option is (d). "3x stronger".

Step-by-step explanation:

The force between two charged particle is given by :

`F=k(q_1q_2)/(r^2)`

If one charge is tripled,
`q_1'=3q`

New force will be :

`F'=(kq_1'q_2)/(r^2)\\\\=3* F`

It means if one of the charges were to triple in strength, then the force will become 3 times of the initial force.
