Consider a system of three point charges ont the x axis. Charge 1 is at x=0, charge 2 is at x=0.20m, and charge 3 is at x = 0.40m. In addition, the charges have the following values: q1 = -19uC, q2=q3=+19uC. Find the the point where E =0 between x =0.20m?
Find the point where E =0 between x = 0.20m and x = 0.40m
Find the point where E =0 between x = 0.20m and x = 0.40m
1 Answer
The situation as described in the problem is shown in the figure.
Let the position where the system charges will have net net intensity
Intensity at N due to
Intensity at N due to
Intensity at N due to
where Coulomb's constant,
So considering the equilibrium we can write
So we have
So location of
