Why is it necessary to accelerate positively charged nuclei to high kinetic energies to cause fusion?(a) To overcome electrical repulsive forces(b) To result in high amount of energy in short period of time(c) To get the isobars and isotopes(d) To get a sustainable reactionI have been asked this question by my school principal while I was bunking the class.I'd like to ask this question from Nuclear Fission & Nuclear Fusion in chapter Nuclear Power Plant of Energy Engineering

Answer»

The correct option is (a) To overcome electrical repulsive forces

The EXPLANATION is: To cause fusion, it is NECESSARY to accelerate POSITIVELY charged nuclei to high kinetic energies to overcome electrical repulsive forces. This is done by rising their TEMPERATURES to hundreds of millions of degree RESULTING in plasma.
