The velocity associated with a proton moving in a potential difference of 1000 V is 4.37×105 ms-1. If the hockey ball of mass 0.1 kg is moving with this velocity, calcualte the wavelength associated with this velocity.





Q.60:- The velocity associated with a proton moving in a potential difference of 1000 V is 4.37×10ms-1. If the hockey ball of mass 0.1 kg is moving with this velocity, calcualte the wavelength associated with this velocity.

 

 

Answer:-
λ = h/mv = 6.626×10-34 kgm2s-1/(0.1 kg) (4.37×105 ms-1) = 1.516×10-28 m
