The magnitude of that other charge will be 9×10⁻⁵ C. The force on the charge is inverse of the distance.
<h3>What is Columb's law?</h3>
The force of attraction between two charges, according to Coulomb's law, is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
The magnitude of that other charge is found as;
Hence, the magnitude of that other charge will be 9×10⁻⁵ C.

Answer:
<h2>90 J</h2>
Explanation:
The work done by an object can be found by using the formula
workdone = force × distance
From the question we have
workdone = 30 × 3
We have the final answer as
<h3>90 J</h3>
Hope this helps you
by the formula of spring force we know that
here we know that
now we will have
now by similar way if the stretch in spring is 0.25 m
force is given by
so it will require F = 250 N force
Hi,
An element’s atomic number tells how many protons an atom of this element has. Protons have a positive electric charge, while electrons have a negative one. If an atom is electrically neutral (as in this case, otherwise it should have been specified) the number of protons and electrons are equal. So, an atom of the element would have 59 electrons.
Hope this helps! If my answer was not clear enough or you’d like further explanation please let me know. Also, English is not my first language, so I’m sorry for any mistake.
