Question

A point charge q1 = 3.65 nC is located on the x-axis at x = 2.00m, and a second point charge q2 = -6.80 nC is on the y-axis at y = 1.00 m What is the total electric flux due to these two point charges through a spherical surface centered at the origin and with radius r1 = 0.735 m? What is the total electric flux due to these two point charges through a spherical surface centered at the origin and with radius r2 = 1.40 m? What is the total electric flux due to these two point charges through a spherical surface centered at the origin and with radius r3 = 2.85 m?

Explanation / Answer

A)Since the first surface does not enclose any charge, the flux through it is 0.

B)This includes only the -6.8nC charge and therefore the flux =q/0=-768N.m2/C

C)This includes both charges and flux=q/0=-3.15nC/0=-356N.m2/C
