Homework Statement
Figure 23-37a shows a narrow charged solid cylinder that is
coaxial with a larger charged cylindrical shell. Both are noncon-ducting and thin and have uniform surface charge densities on their outer surfaces. Figure 23-37b gives the radial component E of the electric field...
but isn't the magnitude effected by the direction or angle?
If I'm applying a force at a 45 degree angle the amount it moves is different than if I apply it at a 90 degree angle.
Homework Statement
In the figure the three particles are fixed in place and have charges q1 = q2 = +e and q3 = 2e. Distance a = 6.00 µm. What is the magnitude of the net electric field at point P due to the particles?
