Question

A cubical volume is bounded by the surfaces x = 0, x = a, y = 0, y = a, z = 0, z = a. The electric field in the region is given by \(\vec E =E _0x\hat i\) Where E₀ = 4 × 10⁴ NC^–1 m^–1. If a = 2 cm, the charge contained in the cubical volume is Q × 10^–14C. The value of Q is____. 

(Take ∈₀ = 9 × 10^–12 C²/Nm²)

Answer 1

The value of Q is 288.
