Question

Calculate the uncertainty in the velocity of an electron of uncertainty in its position is 0. 0001 m . (A) 1.579m/s (B) 0.28m/s (C) 0.579m/s (D) cannot be calculated​

Answer 1

Explanation:

∆p.∆r = h/4π

mv.r = h/4π

∆v = h/4π.m.r

= 6.6*10^-³⁴/4*3.14*9.1*10^-³¹*10^-⁴

after solving carefully...

=> ∆v = 0.579..
