Question

A sphere of radius 5cm has a charge of 31.41 micro coulomb. calculate the surface density of charge​

Answer 1

Answer:

The surface density of charge of the sphere is 999.8 C/ m².

and by the way it is microcoulomb...

Answer 2

Answer:

The surface density of charge of the charge is 999.8 cm/m².

GIVEN :

The radius of the sphere, r = 5 cm.

• 5 × $5 \times {10}^{ - 2} m$

FORMULA :

The surface density of charge = $\frac {q}{a}$

SOLUTION :

→ $\frac {31.41 × \times {10}^{ - 6}c {3.14}$ × $\times {10}^{-4} m²}}$

$\boxed{999.8 \: cm/m²}$

$\therefore$ The surface density of the charge is 999.8 cm/m².
