Question

Problem 6.51

1) Using Heisenberg's uncertainty principle, calculate the uncertainty in the position of a 1.40 −mg mosquito moving at a speed of 1.50 m/s if the speed is known to within ±0.01m/s.

2)Using Heisenberg's uncertainty principle, calculate the uncertainty in the position of a proton moving at a speed of ( 5.50 ±0.01)×104m/s. ( Take the mass of a proton m=1.673×10−27kg.)
