Question

In a particular region of the earth's atmosphere. the electric field above the Earth's surface has been measured to be 155 N/C downward at an altitude of 272 m and 172.5 N/C downward at an altitude of 428 in. Neglecting the curvature of the earth, calculate the volume charge density of the atmosphere assuming it to be uniform between 272 m and 428 in. The permittivity of free space is 8.85 times 10-2 C2/N m2. Answer in units of C/m3

Explanation / Answer

sol S(E1-E2)=?S(h2-h1)/e0 this comes from According to Gauss Law: ?E*dS=?Q/e0, where ?E*dS=S(E1-E2) and ?Q/e0=?V/e0=?S(h2-h1)/e0==> S(E1-E2)=?S(h2-h1)/e0 E1-E2=?(h2-h1)/e0 ?=e0(E1-E2)/(h2-h1) put values
