hi I don't exactly know how to approach this problem
Compute the electric field in air midway bewteen two point charges of 20*10^-8C and -5*10^-8C separated by a distance of 10cm
i was thinking of finding V of both the charges and finding the difference between them
so V1 = k(20*10^-8C)/(.1m) - k(-5*-10^-8C)/(.1m)
where k = 9.0*10^9 N*m^2/C^2
then you know V then you can do V/r = E
am i even close?
thanks :)
