The de-Broglie wavelength associated with a ball of mass 1 kg having k

1.	The de-Broglie wavelength associated with a ball of mass 1 kg having kinetic energy 0.5 J is
Answer» `6.626 xx 10^(-34) m` `13.20 xx 10^(-34) m` `10.38 xx 10^(-21) m` `6.626 xx 10^(-34) Å` Solution :`(1)/(2) MV^(2) = 05 J` `(1)/(2) xx 1KG xx v^(2) = 0.5 J or v^(2) = 1 or v = 1 ms^(-1)` `LAMDA = (h)/(mv) = (6.626 xx 10^(-34) kg m^(2) s^(-1))/(1kg xx 1MS^(-1))` `= 6.626 xx 10^(-34) m`
