Question

The speed of the bullet (m = 50g) and the speed of an electron ( m = 9.1 * 10-28g) are
measured to be the same, namely 300 m/s, with an uncertainty of 0.01%. With what
fundamental accuracy could we have located the position of each, if the position is
measured simultaneously with the speed in the same expt.?

deltaX*deltap=> h/2

deltap=.0001*m*300 where m is the mass of the particle.

delta position= h/(2*deltap)
