STANDARD Physics Charge Distribution MCQ Question
Type: MCQ-conceptual-Medium
If they are brought in contact and separated, then the new surface charge densities on each of the sphere are respectively
A
5σ/2, 5σ/4
B
5σ/3, 5σ/6
C
3σ/5, 6σ/5
D
2σ/3, 1σ/2
Correct Answer
Option B
Detailed Explanation
When two spheres are brought in contact, their charges are shared till their potentials become equal. The new surface charge densities are calculated based on the conservation of charge and equal potential condition.
