You can put this solution on YOUR website! I'm currently doing engineering science (mathematical modelling) and unfortunately i have never taken physics or calculus so i'm confused as how to approach this question.
The electrostatic force, E, between two charged particles is proportional to the charge of each particle, and inversely proportional to the square of the distance between them. Two particles are 0.5m apart. One particle has a charge of 1 coulomb and another a charge of 2 coloumbs. The force beween them is approximately 72×109 Newtons. Find the force between two 1 coulomb particles which are 2m apart.
The formula for E must be:
1.) E = k*(c1*c2)/(d1-d2)^2
First we need to find k (the proportionality constant).
We know that
E = 72*109 = k*((1*2)/.5^2)
Solve the above for k, then substitue the answer for k in:
E = k*((1*1)/(2^2))
