Homework Statement
Calculate the magnitude and direction of the electric field at point Z in
Figure 13, due to the charged spheres at points X and Y.
Homework Equations
E = kq1/r^2
The Attempt at a Solution
Determine each vector component:
Ex = (9.0x10^9 Nm^2/C^2)(50.0 x 10^-6 C) / (0.75m)^2
Ex = 8.0 x 10^5 N/C
Ey = (9.0x10^9 Nm^2/C^2)(10.0 x 10^-6 C) / (0.30m)^2
Ey = 1.0 x 10^6 N/C
Determine sum of vectors:
Ez = ∑E = Ex + Ey = 8.0 x 10^5 N/C + 10 x 10^5 N/C = 1.8 x 10^6 N/C
The answer should be 2.0 x 10^5 N/C
