Answer:
The charge is 
Explanation:
From the question we are told that
The mass of each ball is 
The distance of separation is 
Generally the weight of the each ball is mathematically represented as
where g is the acceleration due to gravity with a value 
substituting values
Generally the electrostatic force between this balls is mathematically represented as
given that the the charges are equal we have
So
Now from the question we are told to find the charge when the weight of one ball is equal to the electrostatic force
So we have
=>
It is about a billion times brighter.
<h3>What is the brightness of a star called?</h3>
- A star's apparent magnitude, or how bright it seems to be from Earth, and absolute magnitude, or how brilliant it looks at a standard distance of 32.6 light-years, or 10 parsecs, are words used by astronomers to describe stellar brightness.
<h3>How bright are planets compared to stars?</h3>
- Although planets and stars light up the night sky, planets usually appear much brighter than most stars.
- Astronomers use astronomical scales to measure the relative brightness of celestial bodies, and many planets fall within the range easily visible to the eye.
