1.	Assertion (A) : The total mass of the protons of a born atom is 6185 times the total mass of electrons.Reason (R ) : Mass of one proton is times the mass of electron.
Answer» Both A and R are true and R is the correct explanation For A. Both A and R are true but R is not the correct explanationfor A. A is true and R is false. A is false and R is true. Solution :Mass of one PROTON is1837 times the mass of an ELECTRON . Hence the totol mass of protons in boron is 9185 times`(5xx1837)`the totalmass of ELECTRONS.
