Question

113. If the uncertainity in velocity of a moving
object is 1.0 x 10-6 ms- and the uncertainty
in its position is 58m, the mass of this object
is approximately equal to that of
(h = 6.626 x 10-34 Js)
1) Helium
2) Deuterium
3) Lithium
4) Electron​

Answer 1

Answer:

Δx×m×Δv=

4π

h

58×m×1.0×10

−6

=

43.1416

6.626×10

−34

m=9.091×10

−31

kg

It is equal to the mass of an electron.

Hence, option C is the correct answer.

Answer 2

Answer:

the uncertainty in velocity of a moving object is 1.0×10−6ms−1 and the uncertainty in its position is 58 m, the mass of this object is approximately equal to that of : (h=6.626×10−34js)
