he following charges are located inside a submarine: 5.20 μC, -9.00 μC, 27.0 μC, and -47 μC. (a) Calculate the net electric flux through the hull of the submarine. N-m²/c (b) Is the number of electric field lines leaving the submarine greater than, equal to, or less than the number entering it? O greater than equal to less than

can you answer all parts please

An insulating sphere of radius R = 3 cm has positive charge uniformly distributed throughout its entire volume. The electric field at the surface of the sphere has a magnitude of E = 5x107 V/m (a) [3 points] Calculate the volumetric charge density p of the sphere (in C/m3) and Calculate the magnitude of the electric field at a point located atr= 1cm, inside the insulator.

A circular surface is inclined about 40° when it is in an electric field of 10000 N/C. The radius of the  circular surface is 9.0 cm and the  angle is made with the area vector and electric field.  Determine the electrical flow on the surface.
