A macroscopic particle of mass 100 g and moving at velocity of 100 cms

1.	A macroscopic particle of mass 100 g and moving at velocity of 100 cms^(-1) will have a de Broglie wavelength of………
Answer» `66xx10^(29)cm` `6.6xx10^(-30)cm` `6.6xx10^(-31)cm` `6.6xx10^(-32)cm` Solution :`m=100g=100xx10^(3)KG` `v=100cm s^(-1)=100xx10^(-2)m s^(-1)` `gammah/(MV)` `(6.626XX10^(34)JS^(-1))/(100xx10^(-3)kGxx100xx10^(-2)ms^(-)` `6.626xx10^(-31)ms^(-1)` =`6.625xx10^(-31)ms^(-1)`
