The overall goal is to find the electric field at the center of the semicircle below. The charge density is not uniform in this case; it depends on the angle via the function lambda(theta) lambda_0 sin theta. This means that there is more charge density near the center of the semicircle than at the tips. a) If you cut out a small amount of arc length along the circle...

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...

Item 25 The electric field was defined as E - Fon a/g, and we used this to find the electric field of a point charge. Using analogous reasoning, what is the gravitational field g of a point mass? Write your answer using the unit vector , but be careful with signs; the gravitational force between two "like masses" is attractive, not repulsive Newton's law of gravity and Coulomb's law are botlh inverse-square laws. Consequently, there should be a "Gauss's law...

4. A flexible plastic rod can be charged and bent into a semicircle. Using the method of "breaking the object" into many point charges and then integrating the electric field from those charges, derive an equation for the electric field components at the center of the semicircle for a rod of length L, bent into a semicircle of radius R, with charge Q. Hints: Use the angle for your position of each "point charge". The length of a small segment...

9. Electric Field Inside an Insulator (25 pts.) A spherical insulator has constant charge density, total charge > 0, and radius B. What is the magnitude of the electric field at a distance B/2 from the center of the sphere? Give the answer in terms of Q, B, and K, where K is the constant from Coulomb's law. Hint: Use Gauss's law.
A plastic rod, shown on the right, has a uniform linear charge density λ and is bent into a quarter circle. Your goal is to find the electric field at the origin.
Week 3: Electric Field of Continuous Charge Distribution HW A plastic rod, shown on the right, has a uniform linear charge density λ and is bent into a quarter circle. Your goal is to find the electric field at the origin. 1 Label an arbitrary small piece of charge dq at an angle θ as shown in the figure. Draw a vector representing the field at the origin from that small piece of charge.2 Write expressions for the x- and y- components...

When we applied Gauss's Law to find the electric field of an infinite sheet of charge, we also treated the sheet as if it was very thin, like a sheet of paper. But if the sheet has an appreciable thickness, we can investigate the field within the sheet as well. Here are two views of a thick sheet of charge with my suggestion for a Gaussian surface, viewed both head-on and at an angle so you can see the distances:...
