The total mass of the protons of a boron...

The total mass of the protons of a boron atom is 6185 times the total mass of electrons.
Reason (R): Mass of one proton is 1837 times the mass of electron.
(a) Both A and R are true and R is the correct explanation for A.
(b) Both A and R are true but R is not the correct explanation for A.
(c) A is true and R is false.
A false and R true.

A

Both A and R are true and R is the correct explanation for A.

B

Both A and R are true but R is not the correct explanation for A.

C

A is true and R is false.

D

A is false and R is true.

Text Solution

Verified by Experts

The correct Answer is:
d
Mass of one proton is 1837 times the mass of an electron. Hence, the total mass of protons in boron is 9185 times (`5 xx 1837`) the total mass of electrons.
