Consider a uniformly distributed thin rod of total charge Q

Consider a uniformly distributed thin rod of total charge Q = 500nC and length L = 2mm situated on the x-axis between x = 0 and x = L.

A) Calculate the magnitude (N/nC) of the electric field at a point x=−1mm on the x-axis.

B) Calculate the magnitude of the electric field at a point y=1mm on the y-axis.

C) Consider a thin rod of zero total charge located on the x-axis, extending from x=−1mm to x=1mm. The part of the rod on negative axis has a uniformly-distributed charge of QL=−500nC, and the part of rod on the positive axis has a uniformly-distributed charge of QR=+500nC. Calculate the magnitude of the electric field at (x,y)=(0.5mm,1mm).

D) Determine the dipole moment (nC⋅mm) of the rod of Part D.
