 Class-12 Nootan ISC Physics Solution  Ch-29 Mass-Energy Equivalence : Nuclear Binding Energy

Que-1: Earth absorbs 10^22 joule energy every day from the sun. What will be the percentage increase in the earth’s mass (6.0 x 10^24 kg) due to this?

Ans- Mass defect in everyday

% Mass increase in the Earth’s mass (6 x 10^24 kg) is

Que-2: Work out the energy equivalence of the rest-mass of electron (9.1 x 10^-31 kg).

Ans- Energy(E) = mc²

Que-3: Find the rest-mass energy of electron in MeV.

Ans- The rest mass Energy = moc²

Que-4: What is the equivalent energy in electron-volt of 1 gram mass?

Ans- E = Δm.c²

Que-5: Calculate the energy equivalent (in MeV) of one-twelfth of the mass of one atom of carbon-12. (ISC 2001)

Ans- Energy = 1/12 x Mass of C. atom x 931.5 MeV

=> 1/12 x 12 x 931.5 = 931.5 MeV

Que-6: The value of one unified atomic mass unit is 1.66 x 10^-27 kg. Calculate the mass of one atom of C^12 in kg. (ISC 2002)

Ans- Mass of one carbon atom
