Q. A 10 Kg block of Iron has which of the following twice in value in comparison to a 5 Kg block of Iron? Inertia Mass Volume Select the correct option from the codes given below:
Answer: 1, 2 & 3
Notes: All three options are correct:

1. Inertia: The 10 kg block of iron will have twice the inertia of the 5 kg block of iron because inertia is directly proportional to mass.
2. Mass: The 10 kg block of iron has twice the mass of the 5 kg block of iron.
3. Volume: Assuming the density of the iron remains the same, the 10 kg block of iron will have twice the volume of the 5 kg block of iron. This is because density is defined as mass per unit volume, and if mass doubles while density remains constant, volume will also double.

So, all three properties, inertia, mass, and volume, will be twice in value for the 10 kg block compared to the 5 kg block of iron.
