b) C) S Figure shows a section of three long charged cylinders centered on the same axis. Central cylinder A has a uniform charge qA +390. What uniform charges qs and qe should be on cylinders B and C so that the net electric field is zero at point 2 (between B and C) and point 3 (outside C)? 9B = 390, 9B = 290, 9c90 9B-390, 9c=0 9B 90. 9c-90 9c=0

A non-conducting sphere 15.0cm in diameter has a total charge of 2.25µC distributed uniformly throughout its volume. Plot the magnitude of the electric field, E, as a function of the distance, r, from the center of the sphere, from r =0cm to r =30.0cm. (The graph must be madeon computer)

A thin cylindrical shell of radius R₁ = 4.5 cm is surrounded by a second cylindrical shell of radius R₂ = 9.5 cm, as in ( Figure 1). Both cylinders are 15 m long and the inner one carries a total charge Q₁ = -0.68 nC and the outer one Q2 = +1.56 nC. Figure RR R₂ 1 of 1 Part A If an electron (m = 9.1 x 10-31 kg) escaped from the surface of the inner cylinder with negligible speed, what would be its speed when it reached the outer cylinder?

The drawing shows two situations in which charges are placed on the x and y axes. They are all located at the same distance of 5.00 cm from the origin O. For each of the situations in the drawing, determine the magnitude of the net electric field at the origin. -l.0 μC +1.0 uC +2.0 uC -3.0 µC +4.0 µC -1.0 uC o! +6.0 uC (b) (a)
