A positive charge is inside an isolated metal spherical shell, as shown in Fig. 15.24. Describe the electric field in the following three regions: between the charge and the inside surface of the shell, inside the shell itself, and outside the outer shell surface. What is the sign of the charge on the two shell surfaces? How would your answers change if the charge were negative?
Answer to relevant Questions(a) Could the electric field due to two identical negative charges ever be zero at some location(s) nearby? Explain. If your answer is yes, describe and sketch the situation. (b) How would your answer change if the charges ...Explain carefully the steps you would use to create an electroscope that is positively charged by induction. After you are done, suppose a charged object was brought near the top of the electroscope and the leaves collapsed. ...Two charges are brought together until they are 100 cm apart, causing the electric force between them to increase by a factor of exactly 5. What was their initial separation distance? Two 0.10-g pith balls are suspended from the same point by threads 30 cm long. (Pith is a light insulating material once used to make helmets worn in tropical climates.) When the balls are given equal charges, they come to ...Three charges, +2.5μC, – 4.8 μC, and – 6.3μC, are located at (-0.20 m, 0.15 m), (0.50 m, -0.35m), and (-0.42m, -0.32m) respectively. What is the electric field at the origin?
