Spherical surfaces at r = 2,4, and 6 cm carry uniform surface charge densities %3D of 20 nC/m², –4 nC/m² and pso, respectively. (a) Find D at r = 1, 3, and 5 cm. b) Determine Pso such that D = 0 at r = 7 m.

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?

A particle of mass 5.4×10^−6 g and a charge of −2 nC starts out traveling horizontallyat 500 m/s straight between two oppositely charged plates separated by 3 cm. The plateshave surface charge densities of 9 µC/m^2Determine the following:a) How long till it impacts either plate?b) How far will it travel horizontally until it impacts one of the plates?
