A certain particle carries 2.5×10-16 C of static electric charge. Calculate the number of electrons present in it.





Q.38:- A certain particle carries 2.5×10-16 C of static electric charge. Calculate the number of electrons present in it.

 

 

Answer:-
Charge on one electron = 1.602×10-19 C
∴ Number of electrons carrying 2.5×10-16 C charge = 2.5×10-16/1.602×10-19 =1560
