A point charge q1q1q_1 = 4.35 nCnC is located on thex-axis at xxx = 2.10 mm , and a second point chargeq2q2q_2 = -6.25 nCnC is on the y-axis at yyy = 1.00 mm.
a)
What is the total electric flux due to these two point chargesthrough a spherical surface centered at the origin and with radiusr1r1r_1 = 0.385 mm ?
b)
What is the total electric flux due to these two point chargesthrough a spherical surface centered at the origin and with radiusr2r2r_2 = 1.50 mm ?
c)What is the total electric flux due to these two point chargesthrough a spherical surface centered at the origin and with radiusr3r3r_3 = 2.80 mm ?
