Detailed explanation-1: -Which one of the following statements is true concerning the spacing of the electric field lines in the vicinity of two point charges of equal magnitude and opposite sign? The spacing indicates the relative magnitude of the electric field.
Detailed explanation-2: -The electric field at a point in space is a measure of the electric force per unit charge on a point charge at that point.
Detailed explanation-3: -EXPLANATION: Electric field lines when goes into the surface or comes out of the surface of a charged body, are always perpendicular to the surface of the charged body. So statement 1 is correct.
Detailed explanation-4: -It does not depend upon the sign of the charge. Hence, the correct answer is the sign of the charge causing the field.
