Question

4. The uncertainty in the position of an electron (mass 9.1 x 10-28 g) moving with a
velocity of 3.0 x 10 cm s-* accurate up to 0.011% will be
al 1.92cm b) 7.68cm c) 0.175cm
d) 3.84cm​

Answer 1

Answer:

1.92

Explanation:

Answer 2

Answer:

a 1.92 cm

Explanation:

velocity is 3×10⁴cm s¹ =300ms‐¹

the velocity is accurte up 0.001%".

it indicates that the uncertainty in velocity is 0.001% of actual value, 300 m s^ {-1} ie uncertainty in velocity (v) =300× 0.001/100=3×10-3ms-¹

v =0.3
