Question

Assertion : Nuclear energy can be produced only by fusion of certain elements.
Reason : Nuclear reactions generate enormous energy.

• A. Both the assertion and the reason are true and the reason is a correct explanation of the assertion.
• B. Both the assertion and reason are true but the reason is not a correct explanation of the assertion.
• C. The assertion is true but the reason is false.
• D. Both the assertion and reason are false.
• E. The assertion is false but reason is true.

Answer 1

The correct option is E The assertion is false but reason is true.

Nuclear energy is non conventional, non renewable resource. Nuclear fission and fusion of selected radioactive materials yields large amount of energy. Nuclear energy is obtained from fusion or fission of atoms of certain elements. Nuclear fusion involves the fusion of the nuclei of two atoms instead of the splitting of atoms that occurs in nuclear fission. A modern nuclear reactor consists of both fusion and fission of atom. The result is the release of enormous quantities of energy.
