Question

Darth Vader and Luke Skywalker are flying around in star fighters. There is a small electrical force of 1.5 Newtons when they are 0.5 meters apart. Assuming the ships have the same electric charge, What is the charge on each ship? *​

Answer 1

Answer:

$q=6.45\ \mu C$

Explanation:

Given that,

The electrical force, F = 1.5 N

The distance between Darth Vader and Luke Skywalker, d = 0.5 m

We need to find the charge on each ship. The formula for the electric force is given by :

$F=\dfrac{kq^2}{r^2}\\\\q=\sqrt{\dfrac{Fr^2}{k}} \\\\q=\sqrt{\dfrac{1.5\times 0.5^2}{9\times 10^9}} \\\\q=6.45\ \mu C$

So, the charge on each ship is equal to $6.45\ \mu C$.
