Question

A ball has a mass of 50 g and speed of 30 m/s. If
the speed can be measured within accuracy of
2%, then the uncertainty in the position is
(1) 2.34 x 10-34 m
(2) 1.76 * 10-34 m
(3) 1.76 * 10-33 m
(4) 0.176 * 10-30 m​

Answer 1

Answer:

find velocity with uncertainty

i.e. 2×30/100 = 0.6 m/s

then find uncertainty in position
