I need help with all questions please

How do the electric field lines from a negative point charge extend? Inward toward the charge. Horizontally away from the charge. Vertically away from the charge. Outward in all directions. + For a closed surface surrounding multiple charges, the electric flux through the surface depends on: The shape of the enclosing surface The distance of the charges from the surface The total charge inside the surface only The value of the individual charges only If the electric flux through a closed surface is zero, what can be concluded? The total charge inside the surface is zero. There are no charges outside the surface. The electric field inside the surface is zero. The surface encloses a perfect conductor. What can be inferred about a closed surface's electric flux if the electric field everywhere on the surface points inward? The surface cannot be in electrostatic equilibrium. The net electric flux is zero. The enclosed net charge is positive. The enclosed net charge is negative. What determines the direction of electric field lines in relation to equipotential surfaces? They intersect equipotential surfaces at a 45-degree angle. They are tangential to the equipotential surfaces. They are parallel to the equipotential surfaces. They are perpendicular to the equipotential surfaces. What determines the sign of the work done in moving a charge from one point to another in an electric field? What determines the sign of the work done in moving a charge from one point to another in an electric field? The magnitude of the charge
