Answer:
Electric force, 
Explanation:
Given that,
Electric charge 1, 
Electric charge 2, 
Distance, 
To find,
The electric force between these two sets of charges.
Solution,
There exists a force between two electric charges and this force is called electrostatic force. It is equal to the product of electric charged divided by square of distance between them.

k is the electrostatic constant


So, the electric force between these two sets of charges is  .

The natural light display called aurora borealis is located in the northern 
hemisphere.
There are two types of aurora which are called aurora borealis and aurora 
australis. The aurora borealis is located in the Northern hemisphere while 
the aurora australis is located in the Southern hemisphere.
They receive their energy through the interaction of charged particles 
on the Sun and Earth to produce the light display. An example 
of the interaction involves solar wind with atoms of the upper atmosphere.

The formula for resonant frequency is:

Given information:

Plug in the given values to find one value of capacitance:

Plug in the given values to find the other value of capacitance:

This gives a range of 2.429 nF to 26.45 nF.
With significant figures taken into account, the range of capacitance is 2.43 nF to 30 nF.
