If uncertainity in the measurement of position and momentum of a microscopic object of mass ' m ' are equal, then the uncertainity in the measurement of velocity is given by the expression
Options
- Ah 4 πm
- Bh 4 π × 1 m
- Ch 4 π × 1 m
- Dh 2 πm
Correct answer
B. h 4 π × 1 m
Step-by-step solution
∆ x ∆ p = h 4 π ∆ x = ∆ p = h 4 π ∆ p   = m ∆ v   m ∆ v   = h 4 π ∆ v   = 1 m h 4 π
