Question

A point charge q1 = 4.40 nC is located on the x-axis at x = 2.10 m , and a second point charge q2= -5.80 nC is on the y-axis at y = 1.10 m .

Part A

What is the total electric flux due to these two point charges through a spherical surface centered at the origin and with radius r1 = 0.610 m ?

Part B

What is the total electric flux due to these two point charges through a spherical surface centered at the origin and with radius r2 = 1.45 m ?

Part C

What is the total electric flux due to these two point charges through a spherical surface centered at the origin and with radius r3 = 2.40 m ?

Part B

What is the total electric flux due to these two point charges through a spherical surface centered at the origin and with radius r2 = 1.45 m ?

Part C

What is the total electric flux due to these two point charges through a spherical surface centered at the origin and with radius r3 = 2.40 m ?

= Q /0
1) No charge is enclosed. = 0

2) Charge enclosed = -5.8 nC
= Q /0 = (-5.80*10^-9) /(8.854*10^-12)
= - 655.0711 Cm/F
Negative sign indicate flux enters the surface.

3) Charge enclosed = [4.40 - 5.80] nC

= Q /0 = (- 1.2*10^-9)/(8.854*10^-12)
= -135.532 Cm/F
