Question
I'm on my last try so I don't want to do this wrong! I got every answer up until question D, but I think I'm just messing up in terms of the units. But I don't want to to risk it
Consider a spherical Gaussian surface and three charges: q1 = 1.90 mC q2 = -2.70 mC q3 = 3.72 mC
Find the electric flux through the Gaussian surface if it encloses a) only charges q1 and q2 b) q2 and q3 c) all three charges.
Correct Answers:
a) -1.02x10^5 N*m2/C
b) 1.15 x 10^5 N*m2/C
c) 3.19 x 10^5 m N*m2/C
And I got this through using the equation, just plugging in the values.
phi = q/eo
eo = 8.8 x 10^-12
******QUESTION I NEED HELP WITH*******
Suppose a fourth charge, Q, is added to the situation described in part C. Find the sign and magnitude of Q required to give zero electric flux through the surface. Answer in units of mC.
*** This means phi = 0. I'm still getting it wrong for some reason, probably because of units.
