A hollow conducting sphere has an inside radius of r1 = 0.17 m and an exterior radius of r2 = 0.27 m. The sphere has a net charge of Q = 5.4E-06 C.   What is the field E1 in N/C 1 m from the sphere's exterior surface? What is the magnitude of the field at a distance of 0.05 m from the center of the sphere?

A charge q1 equal to 0.500 μC is at the origin, and a second charge q2 equal to 0.800 μC is on the x axis at 4.00 cm. Find the force (magnitude and direction) that 0.500-μC charge exerts on 0.800-μC charge. Enter a positive value if the force acts in the +x direction and a negative value if the force acts in the -x direction. (Express your answer to three significant figures.) Find the force (magnitude and direction) that 0.800-μC charge exerts on 0.500-μC charge. Enter a positive value if the force acts in the +x direction and a negative value if the force acts in the -x direction. (Express your answer to three significant figures.) How would your answers change if q2q2 were -0.800 μC? The magnitudes of the forces would rise, while the directions would be the same.   The magnitudes of the forces would rise and the directions would change to opposite.   The directions of the forces would change to opposite, while the magnitudes would be the same Answers would be the same.
