A charge of +5.85 µC resides at the origin. (a) What is the flux through any Gaussian surface enclosing this charge? (b) What is the strength of the field due to the charge at a distance of 8.00 cm from the origin? (c) The charge is surrounded by a sphere, centered at the origin, of radius 8.00 cm. What is the product of the field strength at 8.00 cm and the area of this sphere? (d) Explain why your answers to parts a and c are the same.
