A certain particle carreis `2.5 xx 10^(16) C` of static electric charge .Caculate the number of electrons presenct in it.

Text Solution

Verified by Experts

Static electric charge of particle
(q ) = 2.5 `xx 10^(16) C`
Charge of one electron = 1,6022 `xx 10^(19) C`
`=(2.5 xx 10^(16) C)/( 1.6022 xx 10^(19))
`=1560 ` electrons
