Question

In motion of electrons around nucleus centripetal force is given by ____ *

Answer 1

Answer:

ANSWER:-)

The answer is electricity and magnetism. The atom's center, electron nucleus, is positively charged and the electrons that whirl around this nucleus are negatively charged, so they attract each other. The reason the force is strong is because the atom is so small. The distance between the nucleus and the electrons is about 1 Angstrom (named after a famous scientist); this is 0.00000001 cm (10-8 cm) or about 4 billionth of an inch. Since the electric force varies with the distance between the positive and negative charges like 1 over the distance squared, the force gets large for small distances.

This can be typically called as a centripetal force acting on electon to revolve around nucleus.
