Nuclei | Quiz-01

The difference in mass of ⁷X nucleus and total mass of its constituent nucleons is 21.00 u. The binding energy per nucleon for this nucleus is equal to the energy equivalent of-

Which of the following statements is NOT true for nuclear forces?

The radius of ₁₃X²⁷ nucleus is R. The radius of ₅₃Y¹²⁵ nucleus will be-

(A) 5R/3

(B) (13/53)^1/3 x R

(C) (5R/3)^1/3

(D) (13R/53)^1/3

Assertion- In a nuclear reaction, mass is not conserved but mass and energy are conserved as a single entity called mass-energy.
Reason- Mass and energy are inter-convertible in accordance with Einstein's relation, E = mc².

Assertion- Nuclei having mass number about 60 are most stable.
Reason- When two or more light nuclei are combined into a heavier nucleus, then the binding energy per nucleon will increase.

The binding energy per nucleon of deuteron and helium nucleus is 1.1 MeV and 7 MeV. If two deuteron nuclei fuse to form a helium nucleus, the energy released in the process is-
