List of top Electrical Circuits Questions on Electromagnetic Theory: Gauss's Law and Divergence asked in GATE IN

An electric field in free space is
\[ \vec{E} = (2x+5y+6z)\hat{i} + (5x+4y+10z)\hat{j} + (6x+10y+2z)\hat{k} \ \text{V/m} \]
The charge density is \(\_\_\_\_\) \(\text{C/m}^3\). (\(\epsilon_0\) is the permittivity of free space)
