Please choose the right multiple choices.
THE PROBLEM A solid sphere with radius R=12 m has charge Q=1 nC distributed uniformly throughout its volume. (a) Calculate the potential difference between a location at infinity and a location on the sphere's surface. (b) Calculate the potential difference between a location on the sphere's surface and the location at the sphere's centre. (Hint: See Eample 21.3 on page 385.) PAPER SOLUTION Solve the problem on paper first, including all four IDEA steps. You will become a better physicist that way! Have you finished your paper solution already? Oyes no INTERPRET Identify all of the true statements. k0 A. The electric field strength inside the sphere is at a distance r from the centre _ B. The electric field outside the sphere can be calculated from Gauss's law. C. The electric field strength inside the sphere is zero D. The electric field strength inside the sphere is E. The potential outside the sphere can be calculated from an integral of the electric field. F. The potential inside the sphere can be calculated from an integral of the electric field. G. The electric field inside the sphere can be calculated from Gauss's law. H. None of the above.Explanation / Answer
A
a) Potential at surface- potential at infinity = ( 9 x 10^9 ) (1x 10^-9) / 12= 0.75 V
b) 0 ( because potential at surface and anywhere inside the sphere is same, so difference is 0)
True statments: B, E, G
