Question

A point charge q1 = 3.80 nC is located on the x-axis at x = 2.00 m , and a second point charge q2 = -6.35 nC is on the y-axis at y = 1.10 m .

1) What is the total electric flux due to these two point charges through a spherical surface centered at the origin and with radius r1 = 0.525 m ?

2) 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 ?

3) What is the total electric flux due to these two point charges through a spherical surface centered at the origin and with radius r3 = 2.95 m ?

According to the question provided we know that

Part a) Charge enclosed = zero .As we know the formula = Q /0 in which the charged enclosed = 0.==ANSWER)

Part b) Here we will use the same formula as we used above i.e.

= Q /0 = ( -6.35 * 10 ^ -9 C) / ( 8.85 * 10 ^ -12 ) = -717.5141243 Cm/F ====================ANSWER)

(flux is entering the surface)

Part c) Again we use the same formula as mentioned above

= Q /0 = ( 3.80 * 10 ^ -9 - 6.35 * 10 ^ -9 ) / ( 8.85 * 10 ^ -12 ) = -288.1355932 Cm/F =========ANSWER)
