Question

The uncertainty in the position of an electron (mass
9.1 x 10-28gm) moving with a velocity of
3x104 cm sec-1, uncertainity in velocity is 0.011%
will be:-
(1) 1.92 cm
(2) 7.68 cm
(3) 0.175 cm
(4) 3.84 cm​

Answer 1

Answer:

1.92

Explanation:

The uncertainty in the position of an electron (mass=9.1×10-28g) moving with a velocity of 3.0×104cms-1 accurate up to 0.001% will be. (Use h4π in the uncertainty expression, where h=6.626×10-27erg-s) Δx=1.92cm.
