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 = 1/4πεo

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.
