Question

Figure shows three concentric metallic spherical shells The
outermost shell has charge q 2, the inner most
shell has charge q 1, and the middle shell is
uncharged The charge appearing on the inner surface of outermost
shell is

(1) q 1 + q 2 (2) q 2 2 (3)
–q 1

Aishwarya · Answer

the outermost shell will not experience a charge because of itself
since the distance from it is zero it will experience charge only
due to inner shell that is q1 and since it is repulsive in nature
therefore -q1

Figure shows three concentric metallic spherical shells. The outermost shell has charge q 2, the inner most shell has charge q 1, and the middle shell is uncharged. The charge appearing on the inner surface of outermost shell is (1) q 1 + q 2 (2) q 2 2 (3) –q 1

Figure shows three concentric metallic spherical shells. The outermost shell has charge q ₂, the inner most shell has charge q ₁, and the middle shell is uncharged. The charge appearing on the inner surface of outermost shell is

(1) q ₁ + q ₂ (2) $\frac{q_{2}}{2}$ (3) –q ₁
