In a particular region of the earth’s atmo-sphere, the electric field above the earth’s sur-face has been measured to be 152 N/C down-ward at an altitude of 268 m and 171.5 N/Cdownward at an altitude of 414 m.The permittivity of free space is 8.85 ×10−12 C2/N · m2.Neglecting the curvature of the earth, cal-culate the volume charge density of the at-mosphere assuming it to be uniform between268 m and 414 m.Answer in units of C/m3.
