Question

In the figure a very thin spherical plastic shell of radius 15 cm carries a uniformly-distributed negative charge of -9 nC (-9e-9 C) on its outer surface. An uncharged solid metal block is placed nearby. The block is 10 cm thick, and the left surface of the block is 10 cm away from the surface of the sphere.

Which of the diagrams below best represents the charge distribution on the metal block?
Refer to the arrow diagram to answer the questions about direction. 1. Which arrow best indicates the direction of Eshell, the electric field at the center of the metal block, due only to the charged plastic shell? (a-j) 2. Which arrow best indicates the direction of Eblock, the electric field at the center of the metal block, due only to the charges on the metal block? (a-j) 3. Calculate the magnitude of Eblock, the electric field at the center of the metal block, due only to the charges on the block itself. (Hint: make sure you use the appropriate distance in your calculation.) |Eblock| = ________ N/C WIll rate lifesaver for correct answers before midnight tonight PST 9/15 |Eblock| = ________ N/C WIll rate lifesaver for correct answers before midnight tonight PST 9/15

Explanation / Answer

Answers (a) g since the filed lines are towards the plastic shell (b) j zero magnitude since the metal block is coductor the field inside the matal block is zero (c)The field inside the metal block is zero since the metal block is coductor the field inside the matal block is zero.Because the charge resides on the surface since the metal block is coductor the field inside the matal block is zero.Because the charge resides on the surface
