Could someone please help me with these pre-lab questions for physics? Please show work :)

3. For a single, positive point charge, show that the flux through the surface of a sphere is equal to: geno Co 4. In Faraday's ice pail experiment, a charged object is first suspended inside of the ice pail (Figure 8). The object is then set on the bottom of the pail (Figure 8), giving it a net charge. Draw a diagram showing the charge distribution on the ice pail when the ball is suspended and after the charged ball touches the bottom. Include an explanation of your diagrams.
