The ring on the left has a uniform charge qi and the ring on the right has a uniform charge qz The rings are separated by distance d. Assume the positive x axis peints to the right, through the center of the rings. (Use any variable or symbol stated above along with the following as necessary: k for Coulomb's constant. Assume i is greater than g2, and that both charges are positive.) 42 Need Help? Wweh receipt-untitledpdf ^ Paper1.keorra..docx^ Show all Type here to search

Explanation / Answer

electric field by a ring on the left at some distance from its center is given as

E1 = kq1 (d/2)/((d/2)2 + R2)3/2

electric field by a ring on the right at some distance from its center is given as

E2 = kq2 (d/2)/((d/2)2 + R2)3/2

Net electric field at the center is given as

E = E1 - E2 = kq1 (d/2)/((d/2)2 + R2)3/2 - kq2 (d/2)/((d/2)2 + R2)3/2 = k(q1 - q2) (d/2)/((d/2)2 + R2)3/2
