acc. to gauses law..flux is equal to total charge/e or Q/e as there are six sides of the cube so flux through one surface will be Q/6e

When electric flux is zero then electric field is also zero why?
The electric flux depends on charge, when the charge is zero the flux is zero. The electric field depends also on the charge. Thus when the electric flux is zero , the electric field is also zero for the same reason, zero charge. Phi= integral E.dA= integral zcDdA = zcQ Phi is zcQ and depends on charge Q, as does E.
How does Digital weight measurement work?
The strength of an electric charge generated is directly influenced by weight. When a person steps on a digital scale, the electric resistance is measured and sent through a microchip which then converts the electric strength into pounds.
What is the shape of equipotential surface due to a point charge?
concentric spherical surfaces
A Gaussian surface does not enclose a charge Does it mean that E equals 0 on its surface?
No.there can be electric field on the Gaussian surface even if the charge enclosed by it is zero.However ,net flux will be zero through the surface.
What is dimensional formula of coulomb?
The Coulomb is a unit of electric charge. [Charge] is a fundamental quantity.
What is added to dust particles in the electric dust blower that makes them adhere to surfaces better?

When an electric charge moves through a conductor there is an electric in the conductor?
current
Which part of a circuit is a current?
Current is the flow of electric charge or the rate of the flow of an electric charge through a conductor.
What metal doesn't change when electricity goes through it?
Electric current is a flow of electric charge through a medium
What is the electric field outside a charged spherical shell?
The electric field outside the shell is the same as it would be if all the charge of the shell was concentrated as a point charge in the centre of the shell.

What is the electric field on the surface of the conductor?
The field is zero inside only if any charge is evenly distributed on the surface. That's a mathematical theorem, sorry I don't have the proof handy. But when you measure the electric field inside a charged sphere, the charge you use might be large enough to redistribute the surface charge. In this case the electric field will not be zero. Only if you measure at the centre.
