Question

Suppose 2.10 C of positive charge is distributed evenly throughout a sphere of 1.30-cm radius. 1) What is the charge per unit volume for this situation

Answer 1

`\rho=2.28* 10^5\ C/m^3`

Step-by-step explanation:

Given that,

Charge, Q = 2.1 C

The radius of sphere, r = 1.3 cm = 0.013 m

We need to find the charge per unit volume for this situation. It can be calculated a follows:

`\rho=(Q)/((4)/(3)\pi r^3)\\\\\rho=(2.1)/((4)/(3)\pi * (0.013)^3)\\\\\rho=2.28* 10^5\ C/m^3`

So, the charge per unit volume is
`2.28* 10^5\ C/m^3`.
