Question
A uniform spherical volume charge distribution of radius m, centered at the origin, has a strength of C/m. A point charge of strength C is moved from to in Cartesian coordinate system. The relative permittivity of the medium is and the coordinate values are in meters.The work done during the process is ______ J(Round off to two decimal places)
Correct answer
0.38 to 0.42
Solution
Total charge C. The point charge is C. The work done is . Both points are outside the sphere (, ). J = J.
