Original sentence: If one considers the flux of the electric field vector, E, for a tube in the field about a point charge with sides formed by lines tangent to the the field, the flux for the sides is zero and there is an equal and opposite flux at both ends of the tube
Edited sentence: If one considers the flux of the electric field vector, E, for a tube near a point charge in the field the charge but not containing it with sides formed by lines tangent to the the field, the flux for the sides is zero and there is an equal and opposite flux at both ends of the tube
