Question
the position of both an electron and a helium atom is known within 1nm. further the momentum of the electron is known within 5*10-26 kgm/s. the minimum uncertainity in the measurement of the momentum of the helium atom is
Joshi sir comment
according to Heisenberg principle product of uncertainity in position and momentum of a particle is greater than or equal to h/4π, since uncertanity in position of both the particle are same so same will be the momentum uncertainty minima.
