MY NOTES PRACTICE ANOTHER When an electron moves from A to B along an electric field line in the figure below, the electric field does 3.22 x 10-19 j of work on it. Electric field line - Equipotentials What are the electric potential differences of the following? (a) VB - VA ( b ) VC - VAV ( c) VC - By 2. [-/3 Points] DETAILS HRW10 24.P.008. MY NOTES PRACTICE ANOTHER A graph of the x component of the electric field as a function of x in a region of space is shown in the figure below. The scale of the vertical axis is set by Exs = 50.0 N/C. The y and z components of the electric field are zero in this region. Suppose that the electric potential at the origin is 18 V. Ex (N/C) -E x (m) (a) What is the electric potential at x = 2.0 m? (b) What is the greatest positive value of the electric potential for points on the x axis for which 0 S x $ 6.0 m? (c) For what value of x is the electric potential zero? m 3. [-/2 Points] DETAILS HRW10 24.P.011. MY NOTES PRACTICE ANOTHER A nonconducting sphere has radius R = 2.88 cm and uniformly distributed charge q = +4.50 fC. Take the electric potential at the sphere's center to be Vo = 0. (a) What is V at radial distance r = 1.45 cm? (b) What is V at radial distance r = R
