PHY 102 Electrostatics: Electric Charge and Coulomb's Law Objective Question
Take CBT

Question

How should a continuous distribution of charge be treated when calculating the total electric field?
Options
A As a single point charge at the geometric center.
B As a succession of infinitesimal point charges summed via integration.
Correct Answer
C By multiplying the surface area by the permittivity constant.
D By ignoring the internal charge and only considering the edges.
Correct Answer

Option B is the correct answer.

Detailed Explanation

For objects with charge spread over a volume, surface, or line, we divide the charge into dQ elements and integrate the field contributions: E = ∫ dE.

Hint

Use calculus to sum up tiny 'dQ' pieces.
