The figure shows an uncharged conducting cubic shell and a positive point charge Q outside the shell. There are two lettered points W and X inside the shell where the electric field can be measured. The electric field at points W and X are EW and EX, respectively. Point W is at the center of the cubic shell. Outside the shell are points Y and Z where the charge Q can be placed. All four points are along the same line. Which of the following statements is correct? If the point charge is placed at point Y , EW>EX .

Answer A: If the point charge is placed at point Y , E sub W is greater than E sub X .

Answer B: If the point charge is placed at point Y , E sub W is less than E sub X .

Answer C: If the point charge is placed at point Z , E sub W is greater than E sub X .

Answer D: If the point charge is placed at point Z , E sub W is less than E sub X .

Answer E: If the point charge is placed at point Z , E sub W is equal to E sub X .
