Question

By what factor will the electrostatic force between two charged objects change when the amount of charge on one object doubles?

Answer 1

Answer:

The electrostatic force between two charge doubles when when the amount of charge on one object doubles.

Explanation:

Force between two charge particle $F=\frac{1}{4\pi\epsilon } \frac{q_1\cdot\ q_2}{r^{2} }$

Where,  $\frac{1}{4\pi\epsilon } = constant$

$q_1,q_2\ magnitude\ of\ charges.\\r\ is\ the\ distance\ between\ the\ particles.$

Now suppose as per the question

$q_1= 2 q_1\ with\ q_2\ and\ r\ with\ same\ value.\\Hence\ force\ between\ the\ particle\ F_2 =2 F$

Hence, electrostatic force between two charge doubles when when the amount of charge on one object doubles.
