Vedclass · Answer

(C) Nuclei are positively charged particles. For two nuclei to undergo fusion,they must overcome the strong electrostatic Coulombic repulsion between them.At room temperature,the kinetic energy of the lithium nuclei is insufficient to overcome this repulsive potential barrier.Therefore,they cannot come close enough for the short-range strong nuclear force to take over and bind them together.
