Q. Which of the following statements is incorrect?
I. The charge $q$ on $a_1$ body is always given by $q=$ ne, where $n$ is any integer, positive or negative.
II. By convention, the charge on an electron is taken to be negative.
III. The fact that electric charge is always an integral multiple of $e$ is termed as quantisation of charge.
IV. The quatisation of charge was experimentally demonstrated by Newton in 1912.

Electric Charges and Fields

Solution:

Millikan demonstrated the quantisation of charge experimentally. Charge on electron $=- e =-1.6 \times$ $100^{-19} C$. Addition of charge can occur in integral multiples of $e$.
