358341 Assertion :
A point charge is lying at the centre of a cube of each side in space. The electric flux emanating from each surface of the cube is \(\dfrac{1^{\text {th }}}{6}\) of total flux.
Reason :
According to Gauss theorem, total electric flux through a closed surface enclosing a charge is equal to \(1 / \varepsilon_{0}\) times the magnitude of the charge enclosed.
