Post by: agilleland on Jan 21, 2018 The electric field just outside the surface of a hollow conducting sphere of radius 20 cm has a magnitude of 500 N/C and is directed outward. An unknown charge Q is introduced into the center of the sphere and it is noted that the electric field is still directed outward but has decreased to 100 N/C. What is the magnitude of the charge Q?
a. 1.5 nC b. 1.8 nC c. 1.3 nC d. 1.1 nC e. 2.7 nC Title: The electric field just outside the surface of a hollow conducting sphere of radius 20 cm has a ... Post by: Flamebrain920 on Jan 21, 2018 Content hidden
