Three charges are placed on the x axis. The position of two of the charges are listed
q1 = 5.0 nC is at x = 0 cm
q2 = -9.0 nC is at x = 8 cm
Assume the charges do not move from their appointed positions.
a) At what values of x can a third charge (q3 = 5 nC) be placed so that the force on it = 0 N?
If there is more than one answer for for the previous section, for the rest of the problem, assume the third charge is at the lower value of x.
b) What is the magnitude of the electric field from the first two charges at the location of the third charge?
c) What is the magnitude of the electric field at x = -4 cm?
d) What is the magnitude of the electric field directly above q3?
e) If there is a Gaussian sphere with a radius of 4 cm surrounding q2, then what is the total electric flux through the surface of the sphere from all three charges?
