er 22 State True/False for the following: a) The magnitude of electric force between two-point charges varies directly as the product of charges and inversely as the separation distance between them. b) A combination of 3 protons and 2 electrons would have a net charge of +1.60 x 10-19 C. c) For a positive source charge q, the electric field at observation point P (say), points radially outward from q. d) The permittivity of free space is a constant given by co = 8.8542 x 10-12 C2 / N2.m and can be used in finding Coulomb's constant. e) Electric field lines start from negative charge and terminate onto positive charge a proton, where
