Explanation / Answer

14)

Ey = 9e9*3e-6/(sqrt(13))^2 * (2/sqrt(13)) - 9e9*2e06/(2*2)

Ey = 9e9*3e-6/(13) * (2/(13)^0.5) - 9e9*2e-6/(2*2)

Ey = -3.34 x 10^3 V/m

15)

V = 9e9*3e-6/(13)^0.5 - 9e9*2e-6/(2)

V = -1.51 x 10^3 V

16)

V(3) = 9e9*3e-6/(18)y0.5 - 9e9*2e-6/(3)

V(3) = 363.96 V

dV = V(3) - V(2) = 363.96 - (-1.512e3) = 1876 V

W = q dV = 1e-6 * 1876 = +1.87 x 10^-3 J
