Question

Statement I: A point charge $q_{0}$ is kept outside a solid metallic sphere; the electric field inside the sphere is zero.
Statement II: Induced charge does not contribute to electric field or potential at a given point..

• A. If both statements are true and statement II is correct explanation of statement I.
• B. If both statements are true but statement II is not the correct explanation of statement I.
• C. If statement I is true but the statement II is false.
• D. If both statements are false.

Answer 1

Answer: (C)

Electric field due to $q_{0}$ is towards left and is $\frac{k q_{0}}{r^{2}}$ but electric field due to induced charge is towards right and will have same magnitude $\frac{k q_{0}}{r^{2}}$ so that electric field inside the sphere is zero.
