Question

A point charge q1 = 3.25nC is located on the x-axis at x = 2.15m, and a second point charge q2 = -5.80nC is on the y-axis at y = 1.30m. What is the total electric flux due to these two point charges through a spherical surface centered at the origin and with radius r1 = 0.675 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 = 1.50m? What is the total electric flux due to these two point charges through a spherical surface centered at the origin and with radius r3 = 2.85m?

Explanation / Answer

flux = E.A ( dot product of field and area vectors.)
applying gauss law, qenclosed = 0 .so flux = 0

similarly procees for other cases.
for R= 1.5, q2 is inside the sphere, so flux is positive due to q2
apply gauss law, flux = q2/

for radius 2.85m , flux = q1 + q2 /
