I NEED YOUR HELP TO SOLVE THESE PHYSICS III EXERCISES in which electric field, electric flow and Gauss's law are applied, WITH ITS PROCEDURE, GRAPHICS (if any).

Please write as clearly as possible.

1 - A solid metal sphere of radius 3.00 m has a total charge of 5.50 mC (Micro Coulum).

What is the magnitude of the electric field at a distance of 3.10m from the center of the sphere?

2- The electric field just outside a metal ball of radius 3.25cm is 0.775x103 N/C and points toward the ball.

What is the charge inside the ball?

3- The electric field between two square metal plates is 175 N/C. The plates have edges 1.25m and are 3.0cm apart.

What is the charge on each plate?
