1) Consider a spherical Gaussian surface and three charges: q1 = 1.62?C , q2 = -2.45?C , and q3 = 3.57?C . Find the electric flux through the Gaussian surface if it completely encloses
(a) only charges q1 and q2,
(b) only charges q2 and q3, and
(c) all three charges.
2) A proton is released from rest in a uniform electric field of magnitude 1.00×105 N/C . Find the speed of the proton after it has traveled
(a) 1.10cm and
(b) 13.0cm
