Question

A ring and disc are connected with a string placed on a rough surface and foerce of 10 newton acts on centre of disc then frictional force on ring is...???

Answer 1

Answer:The higher will be Z the more relativistic it will be . The only caveat is that Z = 137 because the Dirac eqation implies that electron 1s will have a greater speed greater than light for Z = 137 .However this is done neglecting the finite extension of the nuclei. Here we know that the ultimate fate of the atom lies in the stability of the nucleus.

The answer is 137.
