A point charge q1 = 3.75 nC is located on the x-axis at x = 1.80 mm , and a second point charge q2 = -6.35 nC is on the y-axis at y = 1.05 m
a) What is the total electric flux due to these two point charges through a spherical surface centred at the origin and with radius r1 = 0.390 m
b)What is the total electric flux due to these two point charges through a spherical surface centred at the origin and with radius r2 = 1.55 mm
c)What is the total electric flux due to these two point charges through a spherical surface centred at the origin and with radius r3 = 2.85 m
