Electric flux coming out of a single Na+ ion is _________ Nm2C-1
A. 1.8*10-8
B. 1.8*10-10
C. 5.4*10-8
D. 3.6*10-8
Answer:A
Electric flux coming out of a single Na+ ion is _________ Nm2C-1
A. 1.8*10-8 B. 1.8*10-10 C. 5.4*10-8 D. 3.6*10-8
Explanation: A single Na+ ion means a single sodium atom without an electron. The charge of the ion is the same as the charge of an electron but positive i.e. +1.602*10-19C. Therefore, applying Gauss’s Law, electric flux coming out of the ion = \(\frac {charge \, of \, the \, ion}{\varepsilon}\). Substituting the values, we get flux = 1.8*10-8 Nm2C-1.
