Question:

A charge of 100 C is evenly spread on a square plate of side 10 m and negligible thickness. What is the surface charge density ?

Options:

100 C m^-2

1 C m^-2

110 C m^-2

10 C m^-2

Correct Answer:

1 C m^-2

Explanation:

Surface charge density : σ = Q/S

Q = 100 C ; S = 10 m x 10 m = 100 m²

σ = 1 C m^-2
