Next two questions: We have a ring with radius R = 3 m with linear charge density λ = 50 μC/m. We have a point charge q = 80 μC that moves along the z-axis through the center of the ring. Point S is zS = 16 meters above the center, and point P is zP = 2 meters above the center. Remember that the electric field along the z-axis above a ring is E→ring = 2πkλRz(z2+R2)3/2 z^Change in potential energy from a ring 1 point Find the change in energy from point S to point P.

We have an infinitely long wire, again with linear charge density λ = 10 μC/m. We have a point charge, again with q = 75 μC. Point S is zS = 10 m away from the wire on the z-axis, point P is zP = 5 m away from the wire on the z-axis, and point T is yT = 5 m away from the wire on the y-axis. Remember that the electric field at a distance r away from a wire is E→wire = 2 kλrr^ Figure 2: Figure for Problems 3-5 3.

The figure below shows two lines of charge in cross-section coming out of the page. Each line of charge has a linear charge density of 7.90 nC/cm and they are separated by a distance d = 20.8 cm. What is the magnitude of the electric field at the dot, a point y = 5.70 cm above the midpoint between the lines? Electric field magnitude: ◻
