Dr. Abdus Salam of Pakistan was one of the contributors to the unification of

A. Electromagnetic force and gravitational force
B. Electromagnetic force and weak nuclear force
C. Gravitational force and weak nuclear force
D. Weak nuclear force and strong nuclear force
E. None of above

Check Answer

The correct answer is B) Electromagnetic force and weak nuclear force.

Dr. Abdus Salam was a Pakistani theoretical physicist who made important contributions to the unification of the electromagnetic force and the weak nuclear force, also known as electroweak unification. These two fundamental forces are responsible for the interactions of electrically charged particles, like electrons and protons, in atoms and molecules and it also responsible for some nuclear reactions like beta decay.

He proposed a theoretical model in which the electromagnetic force and the weak force were described as different manifestations of a single underlying force, and this idea was later incorporated into the electroweak theory developed by Sheldon Glashow, Abdus Salam and Steven Weinberg independently. This theory was eventually incorporated into the larger framework of the standard model of particle physics which unifies the electromagnetic force, weak force, and strong force and which also provides a theoretical explanation for the behavior of subatomic particles and the fundamental forces that govern them.

Salam’s contributions to theoretical physics led to the prediction of new particles and the discovery of the W and Z bosons, these discoveries were experimentally verified at CERN’s Super Proton Synchrotron (SPS) and Large Hadron Collider (LHC) For his pioneering work in electroweak unification and his contributions to the development of the standard model of particle physics, Abdus Salam was awarded the Nobel Prize in Physics in 1979.
