Answer» Solution :a. For a very small dust PARTICLE of radius `10^(-6)m(1mu m)`, density `rho=10^(4)kg//m^(3)` moving with a velocity of 0.01 m/s, its momentum p is `p=mv=(4)/(3)pi r^(3) rhov=(4)/(3)pi xx (10^(-6))^(3)xx10^(4)xx0.01` `p ~~ 4xx10^(-16)"kg m"//s` de Broglie wavelength associatedwith this particleis `lambda=(H)/(p)=(6.625xx10^(-34))/(4xx10^(-16))~~1.6xx10^(-18)m` This value of `lambda` is extremely small COMPARED to the dimension of any PHYSICAL system. |
