Question

Calculate the momentum of a moving particle having wavelength 300 pm

Answer 1

Answer:

Momentum=3.313×10^-24kgms-

Explanation:

Here,de-broglie wavelength.

wavelenght=h/mv

200× 10^-12=6.626×10^-34/p[1pm=10^-12m,h=6.626×10^-34]

p=6.626×10-34/200×10^-12

p=6.626×10-34/2×10^-10

p=3.313×10^-34+10

p=3.313×10^-24kgms-
