| Additional question | Use Coulomb's law to calculate the electric force on an electron (Q = -1.6 x 10-16 C) exerted by a single proton if the particles are 0.53 x 10-10 m apart. The constant k in Coulomb's law is 9.0 x 109 Nm2/C2. (The unit N is the newton, the SI unit for force (answer: -8.2 x 10-8 N) | |||||||||
