A large conducting plane has a surface charge density 1*10^-4 C/m2. Find the electrostatic energy stored in a cubical volume of edge 1 cm in front of the plane.

Question

Arun · Answer

Here, σ = 1.0×10-4 Cm-2 a = 1.0×10-2 m V = a3 = 1.0×10-6 m3 Electric field due to an infinite conducting plane is E = σ/εo Electric energy stored per unit volume is given by u = ½ (εoE2) Energy stored in the given volume U = ½εoE2a3 => U = ½εo (σ/εo ) 2a3 => U = a3σ2/2ε0 => U = 1.0×10-6 ×(1.0×10-4)2/(2×8.85×10-12) => U = 5.6×10-4 J
