Plot the graph of the electrical field

Graph Help!

Plot the graph of the electrical field created by a point charge of 10^-6 C as a funtion of distance to the charge. Plot the graph for the range of the distances from 0.1m to 1m



Should I use this equation... E= Q/(4.pi.e)x(d^2) as this is for
electric field strength and not eletric field created as asked?

If i do use thsi equation,
Do I need a value for e or can i ignore the 4.pi.e and just use E= Q/(d^2)
Do I graph the value of E to the correseponding value i used for d?
Should the graph be an inverse square graph??

Thanks for your help.

You can use E = k*q/r² where k = 1/4πε_o

That's k= 9*10⁹

Since your scale is a concern as it spans a range of input that is a factor of 10, then your y-axis needs to span a factor of 100.

I would suggest using the equation E= kQ/(d^2), where k is the Coulomb's constant and Q is the point charge. This equation is specifically for electric field strength, which is what you are trying to graph. You can ignore the 4πε term if you use k, as it is just a constant that accounts for the units used.

To plot the graph, you can use any value for Q, as long as it is consistent throughout the graph. As for the range of distances, I would suggest starting from 0.1m and increasing in small increments (e.g. 0.1m, 0.2m, 0.3m, etc.) up to 1m. This will give you a good range of data points to plot on the graph.

The graph should be an inverse square relationship, as the electric field strength is inversely proportional to the square of the distance from the point charge. This means that as the distance increases, the electric field strength decreases. So, the graph should show a downward curve.

I hope this helps! It is always important to make sure you are using the correct equation and units when plotting graphs in science. Good luck with your graph!
