WebAll charged objects in nature carry charges that are integral multiples of the basic quantity of charge, qe, any charge Q: Q = n qe ∣ qe ∣ = 1×10−19 C. b. How many electrons must be removed from a neutral object to leave a net charge of 0. μC? 2. COULOMB’S LAW Three charges, lie along the x axis as shown: q 1 = 6 μC, q 2 = -2 μC. WebDefinition. An electronvolt is the amount of kinetic energy gained or lost by a single electron accelerating from rest through an electric potential difference of one volt in vacuum. Hence, it has a value of one volt, 1 J/C, multiplied by the elementary charge e = 1.602 176 634 × 10 −19 C. Therefore, one electronvolt is equal to 1.602 176 634 × 10 −19 J. ...
