Question:
Two metallic spheres of radii 1 cm and 3 cm are given charges of -1×10⁻²C and 5×10⁻²C respectively. If these are connected by a conducting wire, the final charge on the bigger sphere is
Two metallic spheres of radii 1 cm and 3 cm are given charges of -1×10⁻²C and 5×10⁻²C respectively. If these are connected by a conducting wire, the final charge on the bigger sphere is
Show Hint
Connected conductors share charge in proportion to their radii.

- 2×10⁻²C
- 3×10⁻²C
- 4×10⁻²C
- 1×10⁻²C
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Total charge: Q=4×10⁻²C
Step 2: Charges distribute proportional to radii.
Step 3: QB=(3)/(4)×4×10⁻²=3×10⁻²C
