Question

Two isolated metallic spheres of radii R and 2R are charged such that both of these have same charge density s. These sphere are located far away from each other and connected by a thin conducting wire, the new charge density on the bigger sphere-

• A. $\frac{3\sigma}{2}$
• B. $\frac{5\sigma}{6}$
• C. $\frac{6\sigma}{5}$
• D. $\frac{2\sigma}{3}$

Answer 1

Answer: (B)

$\frac{5\sigma}{6}$

Answer 2

q = It = 8 × (10 × 60) = 4800 C = 480 AbC
