Statement-1: `1am u.=933MeV`
Statement-2: It follows form `E=mc^(2)`

A

Statement-1 is true, Statement-2 is true and Statement-2 is correct explanation of Statement-1.

B

Statement-1 is true, Statement-2 is true, but Statement-2 is not a correct explanation of Statement-1.

C

Statement-1 is true, but Statement-2 is false

D

Statement-1 is false, but Statement-2 is true.

Text Solution

Verified by Experts

The correct Answer is:
B

Both the statement are true, but the explanation is inadequate. Infact, `1a.m.u.=1.66xx10^(-27)kg` form `E=mc^(2)=1.66xx10^(-27)(3xx10^(8))^(2) "joule"=(1.66xx9xx10^(-11))/(1.6xx10^(-3)) MeV~~933MeV`
