A certain particle carries 2.5 xx 10^(-16) C of static electric charge

1.	A certain particle carries 2.5 xx 10^(-16) C of static electric charge. Calculate the number of electrons present in it.
Answer» Solution :Charge CARRIED by one electron `= 1.6022 XX 10^(-19) C` `:.` Electrons present in particle CARRYING `2.5 xx 10^(-16) C " charge" = (2.5 xx 10^(-16))/(1.6022 xx 10^(-19)) = 1560`
