Question

Part A.) The electric flux through a spherical surface is 4.0\times 10^4~\text{N}\cdot\text{m}^2/\text{C}4.0×10 ​4 ​​ N⋅m ​2 ​​ /C. What is the net charge enclosed by the surface?

Part B.) The electric field 10.0 cm from the surface of a copper ball of radius 5.0 cm is directed toward the ball’s center and has magnitude 9.0*10^2N/C. How much charge is on the surface of the ball?

Select the correct answer

a.) 2.2*10^{-10} . b.)-1.25*10^{-10} . c.)-1.0* 10^{-9} . d.)-4.5* 10^{-10) . e.)-8.4* 10^{-10}

Part C.) A positive charge, q = 15.315.3 nC is placed at the center of a 1 m wide cube. Calculate the electric flux, \Phi_EΦ​E​​, passing through the right face of the cube, as shown in blue in the figure below.
