Question

In a particular region of Earth's atmosphere, the electricfield above Earth's surface has been measured to be 155 N/C downward at an altitude of 280 m and 169 N/C downward atan altitude of 430 m. Calculate the volumecharge density of the atmosphere, assuming it to be uniform between280 and 430m. Please provide answer in C/m3. Thank you in advance.

Explanation / Answer

we know flux = EA - E 'A where E ' = 155 N / C            E= 169 N / C So, flux = 14 A also we know flux = q / from this charge q = flux *                             = 14 A * 8.85 * 10 ^ -12 Volume charge density = q / V                                      = q / (A *(430 m - 280 m ) )                                      = (123.9* 10 ^ -12 ) / ( 150                                      = 0.826 * 10 ^ -12 C / m^3
