Answer:
We have the relation,
(∆ x) /(∆ v) = h/4πm......... 1
Here, h= 6.626x 10^-34 JS= 6.626x 10^-27 erg sec, ∆ x= 1 nm= 1x 10^-7 cm
We know,
m= 9.1x 10^-28 g
∆ v= 6.626x 10^-27 erg sec/4x 3.142x 9.1x 10^-28 gx 1x 10^-7 CM
= 6.62x 10^-27 /114.37x 10^-35 CM/sec
= 0.579x 10^ 7 CM/ sec....
Thank you
