Question

Surface charge density on sphere radius 5 cm, charge 1 μC?
Options
A 3.18×10⁻⁵ C/m²
Correct Answer
B 31.8×10⁻⁵ C/m²
C 3.2×10⁻⁵ C/m²
D 6.4×10⁻⁵ C/m²
Correct Answer

Option A is the correct answer.

Detailed Explanation

σ = Q/(4πr²) = 10⁻⁶/(4π×0.0025) = 10⁻⁶/(0.031416) = 3.18×10⁻⁵ C/m².

Hint

σ = Q/(4πr²).
