Question: Number of electrons in one coulomb of charge will be [MP PMT/PET 1998; Pb. PMT 1999; AIIMS 1999; RPET 2001]
Options:
A) $ 5.46\times 10^{29} $
B) $ 6.25\times 10^{18} $
C) $ 1.6\times {{10}^{+19}} $
D) $ 9\times 10^{11} $
Show Answer
Answer:
Correct Answer: B
Solution:
$ n=\frac{q}{e}=\frac{1}{1.6\times {{10}^{-19}}}=6.25\times 10^{18} $
