Question

A uniform spherical volume charge distribution of radius 22 m, centered at the origin, has a strength of 3π×106\frac{3}{\pi} \times 10^{-6} C/m3^3. A point charge of strength π×8.854×1012\pi \times 8.854 \times 10^{-12} C is moved from (3,0,4)(-3, 0, -4) to (0,0,4)(0, 0, 4) in Cartesian coordinate system. The relative permittivity of the medium is 11 and the coordinate values are in meters.
The work done during the process is ______ μ\mu J
