Question

Large energy released in atomic bomb explosion is mainly due to:

• A. conversion of heavier to lighter atoms
• B. products having lesser mass than initial substance
• C. release of neutrons
• D. release of electrons

Answer 1

The correct option is B products having lesser mass than initial substance

$\bullet$Large energy released in atomic bomb explosion is mainly due to products having lesser mass than initial substance.

$\bullet$The mass difference is converted to energy.

This is responsible for release of large amount of energy.

Relation b/w mass and energy is given as

$E=\left(\Delta m\right).c^2$

where,

c is the speed of light (in S.I. units).
