If uncertainities in the measurement of position and momentum of a microscopic object of mass ' m are equal, then the uncertainty in the measurement of velocity is given by the expression

Options

  1. Ah 4 m
  2. Bh 4 1 m
  3. Ch 4 1 m
  4. Dh 2 m

Correct answer

B. h 4 1 m

Step-by-step solution

According to Heisenberg's uncertainity principle. It is impossible to determine simultaneously the position and momentum of moving particle thus. x p h 4 But, p=m v array rlrl & & v^2 & = h m^2 4 or & v & = h 4 1 m array
