+4 +Q a. Find the electric Field vector E at point P (0, +a). (Calculate the magnitude, and draw b. c. d. the vector in the picture.) Sketch the electric field lines. Find the electric Field E at (x, 0) for x >a Find out the location (x, y) where the electric Field E becomes zero. (Hint: Use the solution of e).
< Question 14 of 25 > The electric field in a region of space increases from 0 to 3400 N/C in 3.10 s. What is the magnitude of the induced magnetic field B around a circular area with a diameter of 0.420 m oriented perpendicularly to the electric field? B = I
1. In lecture, we derived the electric field a height z above the center of a thin ring of charge with constant charge per unit length λ. Let's assumie here that λ > 0. Suppose a negative point charge q with mass m s placed a very small distance above the center of the ring. Show that the point charge undergoes simple harmonic motion and find the frequency of small oscillations. Hint: show that near the center of the ring...
