Two point charges,separated by 1.5 cm,have charge values of +2.0 and -4.0 µC,respectively.Suppose we determine that 10 field lines radiate out from the +2.0-µC charge.If so,what might be inferred about the -4.0-mC charge with respect to field lines?

Question

The number of field lines is proportional to the magnitude of the charge. Since the -4.0 µC charge is twice the magnitude of the +2.0 µC charge, it will have twice the number of field lines, but they will radiate inwards because it is a negative charge.
