C. neutron​

Answer 1

QUESTION:- Which particle has a mass of 9.11 x 10^-28g and charge of -1?

OPTIONS:-

A. electron

B. proton

C. neutron

ANSWER:-

CHARGE ON PROTRON IS +1 AND IT HAS MASS OF
`1.6 * 10 {}^( - 27)` SO IT CANNOT BE URE ANSWER

THERE IS NO CHARGE ON NEUTRON AND HAS MASS ALMOST EQUAL TO THE PROTON SO IT ALSO CANNOT BE URE ANSWER

MASS OF THE ELECTRON:-
`9.11 * 10^( - 28)`

CHARGE ON ELECTRON:-
`-1`

SO URE ANSWER IS ELECTRON
