question_answer 57)

A certain particle carries \[2.5\times {{10}^{-16}}C\] of static electric charge. Calculate the number of electrons present in it.

Answer:

Let n electrons are present in the charged particle. \[n\times {{q}_{e}}=2.5\times {{10}^{-16}}\] \[n\times (1.6\times {{10}^{-19}})=2.5\times {{10}^{-16}}\] \[n=1562\] electrons
