Question

State whether True or False :
At nanoscale, laws of Newtonian mechanics fail.

• A. True
• B. False

Answer 1

The correct option is A True

Quantum mechanics is required to understand the behavior of nanoscale systems because Newtonian theories collapse and fail at this scale. If Newtonian laws governed the working of atoms, then negatively charged electrons would be attracted to the positively charged nucleus of the atoms and the two would collide, but this does not happen.
