A) \[1.6\times {{10}^{-19}}C\]
B) \[4.8\times {{10}^{-19}}C\]
C) \[8\times {{10}^{-19}}C\]
D) \[6\times {{10}^{-19}}C\]
Correct Answer: D
Solution :
According to quantization of charge, any charge will be an integer multiple of a smallest charge (e) \[Q=\pm ne\] where \[n=1,2,3...\] and \[e=1.6\times {{10}^{-19}}C\] In the given charges only \[6\times {{10}^{-19}}C\]is not an integer multiple of e. Therefore, this charge is not possible.
