Question

a uniformly charged sphere carries a
total charges of 2π x 10^-12C it's
radius is 5cm and is placed in
vaccum. Determine it's surface charge density​

Answer 1

To Find:

Determine it's surface charge density​

Solution:

Surface density is defined as charge per unit area.

б=charge/area

Calculation:

б=[2π ˣ 10⁻¹² ˣ 10⁴]/[4π(5)²]

б=(2 ˣ 10⁻¹⁰)c/m²

Answer:

(2 ˣ 10⁻¹⁰)c/m²
