Electrostatics Question 184
Question: A conductor has $ 14.4\times {{10}^{-19}}coulombs $ positive charge. The conductor has (Charge on electron $ =1.6\times {{10}^{-19}}coulombs $ )
Options:
A) 9 electrons in excess
B) 27 electrons in short
C) 27 electrons in excess
D) 9 electrons in short
Show Answer
Answer:
Correct Answer: D
Solution:
Positive charge shows the deficiency of electrons. Number of electrons $ =\frac{14.4\times {{10}^{-19}}}{1.6\times {{10}^{-19}}}=9 $
