Two point charges with charge q each are found on the y axis at y d and y d Show that the resultant electric field on the x axis is E Kq xdxx

$($b Now suppose there are four charges, each with charge q Two of them are on the y axis at y d and y  d and the other two are on the Z-axis at z d and z  d 

Find the electric field on the x axis. 

$($c Finally, suppose instead of point charges, there is a charged ring with radius d and total charge q centered in the yz plane. Argue for and write what the electric field is on the x axis.d A uniformly charged sheet has area A and total charge Q We then cut out a ring with radius d from the sheet so that a charge q is now missing. What is the electric field along the axis of the cut out ring and close to the sheet 

Answer rating: 100% (QA)

a To find the resultant electric field on the xaxis for two point charges q2 each located at y d on the yaxis we can use the principle of superpositio... View the full answer
