A certain particle carries `-2.5 xx 10^(-16)C` of static charge. Calculate the number of electrons present in it.

Text Solution

Verified by Experts

`"No.  of electrons "= ("static charge e")/("coulomb charge of each "e^(-))=(2.5xx10^(-16)"coulomb ")/(1.602xx10^(-19)"coulomb")`
`=1.56xx10^(3)" electrons "= "1,560 electrons"`.
