Consider a long cylindrical charge distribution of radius R = 15 cm with a uniform charge density of ? = 14 C/m3. Find the electric field at a distance r = 31 cm from the axis.
Given that
Uniform charge density (lamda) = 14 C/m3.
Find the electric field at a distance r = 31 cm =0.31m from the axis.
We know that E =lamda/2pie0r =14/2*3.14*8.85*10-12*0.31 =0.812*1012C/m2
=81.2*1010C/m2
