Question

A positively charged sphere is placed near a neutral block of nickel, as shown in the figure below Charged sphere Neutral nickel block (a) Which of the diagrams in the figure below best represents the equilibrium distribution of charge on the neutral nickel block? o c b) At location p inside the nickel block the electric field due to the charged sphere is 21 , o, o N C. At equi brium, which of the following statements must be true? The electric field at location P due only to charges on the surface of the nickel block is (0, o, o) Nic. O It is not possible to determine the electric field at location P due only to charges on the surface of the nickel block Because the net electric field at location P is (o, 0, 0) N/C, the field at P due only to charges on the surface of the polarized nickel block must be (211, o, o) N/C.

Explanation / Answer

Positively charged sphere will attaract negative charges at the end near to it, therefore positive charges will remain in the far end

Answer: B
