Consider N equal point charges evenly spaced on an imaginary circle of radius R. What is the electric field at the center of the circle? The answer is obviously zero, when N is even. What if N is odd (3,5,7,...)? Explain your reasoning.

Find the ratio of q/Q for the E-field to be zero at adistance of z = 3.52R for the charge distributionand geometry of problem #30 of the text. a isthe charge on the LARGER ring. Q is the chargeon the SMALLER ring.

A uniformly charged rod of length L and total charge Q lies along the x axis as shown in in the figure below. (Use the following as necessary: Q, L, d, and ke.) Ey= P d Ⓡ (a) Find the components of the electric field at the point P on the y axis a distance d from the origin. Ex= Eyz (b) What are the approximate values of the field components when d >> L? Ex L Explain why you would expect these results. This answer has not been graded yet. Need Help? Read It
