QuestionElectrostatics / potential
The ratio of electrostatic potentials at a distance of 1 angstrom from the proton (charge = \(1.6\times10^{-19}\) C and mass = \(1.67\times10^{-27}\) kg) and from the electron (charge = \(1.6\times10^{-19}\) C and mass = \(9.1\times10^{-31}\) kg) would be
- (a) 1 : 1
- (b) 1·67 : 9·1
- (c) 1·67 : 0·00091
- (d) 1 : 2
