Question
The speed of an electron having a wavelength of 10-10 m is
Options
A.4.24 × 106 m/s
B.5.25 × 106 m/s
C.6.25 × 106 m/s
D.7.25 × 106 m/s
Solution
We know that De-Broglie wavelength is
mv =
⇒ λ = 
10-10 =
v =
= 7.25 × 106
mv =
⇒ λ = 10-10 =
v =
= 7.25 × 106 Create a free account to view solution
