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
