Question

a sohere of raeius 100cm has a charge of 2pie/3 its surface charge density will be​

Answer 1

Given ,

Radius of sphere = 100 cm or 1 m

Charge on sphere = 2π/3

We know that , the amount of charge present in a given area is called surface charge density

$\sf \hookrightarrow Surface \: charge \: density = \frac{ \cancel{2\pi}}{3 \times \cancel{4\pi }\times {(1)}^{2} } \\ \\\sf \hookrightarrow Surface \: charge \: density = \frac{1}{6} \\ \\ \sf \hookrightarrow Surface \: charge \: density = 0.16 \: \: C/ {m}^{2}$

Hence , the surface charge density is 0.16 C/m²
