Question

A point charge q_1 = 3.00 nC is located on the x-axis at x = 2.30 m, and a second point charge q_2 = -5.85 nC is on the y-axis at y = 1.15 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 r_1 = 0.475 m ? What is the total electric flux due to these two point charges through a spherical surface centered at the origin and with radius r_2 = 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 r_3 = 2.40 m ?

Explanation / Answer

Part A )

charge enclosed in r = 0.475m is zero

Flux = Qbet/epsilon

Flux = 0 ( answer)

Part B)

Flux = Qnet /epsilon

Flux = -5.85 x10^-9/epsilon

Flux = 660.718 Nm^2/C

Part C)

charge enclose in re = 2.4 m

Qnet is = 3-5.85 = -2.85nC

Flux = Qnet /epsilon

Flux = 321.88Nm^2/C
