a uniform electric field of magnitude 4.6 ✕ 104 n/c passes through the plane of a square sheet with sides 3.0 m long. calculate the flux (in n · m2/c) through the sheet if the plane of the sheet is at an angle of 60° to the field. find the flux for both directions of the unit normal to the sheet. unit normal with component parallel to electric field n · m2/c unit normal with component antiparallel to electric field n · m2/c
