The velocity associated with a proton moving in a potential difference of 1000 V is 4.37 xx 10^(5) m s^(-1). If the hockey ball of mass 0.1 kg is moving with this velocity, calculate the wavelength associated with this velocity?

The velocity associated with a proton moving in a potential difference

1.	The velocity associated with a proton moving in a potential difference of 1000 V is 4.37 xx 10^(5) m s^(-1). If the hockey ball of mass 0.1 kg is moving with this velocity, calculate the wavelength associated with this velocity?
Answer» Solution :`lamda = (h)/(mv) = (6.626 xx 10^(-34) kg m^(2) s^(-1))/((0.1lh) (4.37 xx 10^(5) MS^(-1))) = 1.516 xx 10^(-28) m`
