Question

Calculate the momentum of electron if their wavelength is 2a given h=6.626*10^-34js and m=9.1*10^-31 kg

Answer 1

⭐⭐⭐ Hey mate!!⭐⭐⭐

__________________________________________________________

As

⚡Lembda = h/p

⚡And p=mv

Here,

⚡Lembda is wavelength

P=momentum

h is PLANK'S constant

Now,

⚡⚡Given lembda=2A°

h=6.67×10^-34

P=6.67×10^-34/2×10^-10

P=3.33×10^-24

Hope it will help you...✌️✌️
