1.4.2 Electric field of a uniformly charged hoop Our goal here will be to find the electric field of a uniformly charged (thin) hoop. Our hoop has a charge Q uniformly distributed over a hoop with radius R, and is oriented perpendicular to the plane of the paper. We are interested in finding the electric field at the point P, a distance r away from the center of the hoop. See the figure below. do In your answers below, you...

A sphere of radius R has total charge Q. The volume charge density (C/m3) within the sphere is ρ(r)=C/r2, where C is a constant to be determined. The charge within a small volume dV is dq=ρdV. The integral of ρdV over the entire volume of the sphere is the total charge Q. Use this fact to determine the constant C in terms of Q and R. Hint: Let dV be a spherical shell of radius r and thickness dr. What...
RC-1A charge +Q is evenly distributed around a semicircle of radius R in the x-y plane as shown to the right. a) Use dq charge elements to explain why the net field at the center of the semicircle (the origin) has no y component. Use a drawing like the one shown in your explanation. b) Apply Coulomb's law to calculate the strength (magnitude) of the net electric field at the origin in terms of K, Q, R and any other...
