The figure shows a collection of point charges and the intersection of a closed surface with the screen. To three significant figures, determine the electric flux through the closed surface. (Let 91-7 nC, q2 = 9 nC. 93-8nc, and q4 = 6 nC.) 1 nC 92 Closed surface -5 nC Part 1 of 2 Read the problem carefully at least once. Be sure to notice the quantities that are known and those quantities that must be found. The known quantities are the shape of the closed surface and the values and locations of each charge te Gaussian surface. Identify an appropria The closed surface is identified in the problem statement and illustrated in the figure. Apply Gauss's law. Applying Gauss's law means taking the equation Qinside and evaluating each term. The electric flux through the closed surface is the unknown quantity to be determined, inside is the net charge contained with the closed surface, and the constant -1/4ke-8.85 × 10-12 C2 (N m) is the permittivity of free space. What is the value of inside, the net charge contained within the closed surface? Qinside 28 nC O Qinside = 23 nC Qinside = 17 nC Qinside = 22 nC o none of the above

Explanation / Answer

a) Qinside= 7 n C +9 nC+8 nC +6 nC- 2nC= 28 nC

b) flux=28 x 10^-9/ 8.85 x 10^-12= 3.164 x 10^3
