Vedclass · Answer

(A) The de Broglie wavelength $\lambda$ is given by the formula $\lambda = \frac{h}{mv}$.Given: Mass $m = 20 \, g = 20 	imes 10^{-3} \, kg = 0.02 \, kg$.Velocity $v = 100 \, ms^{-1}$.Planck's constant $h = 6.626 	imes 10^{-34} \, Js$.Substituting the values into the formula:$\lambda = \frac{6.626 	imes 10^{-34} \, Js}{0.02 \, kg 	imes 100 \, ms^{-1}}$$\lambda = \frac{6.626 	imes 10^{-34}}{2} \, m$$\lambda = 3.313 	imes 10^{-34} \, m$.Therefore,the correct option is $A$.

$A$ $20 \, g$ object is moving with a velocity of $100 \, ms^{-1}$. The de Broglie wavelength (in $m$) of the object is [Planck's constant $h = 6.626 \times 10^{-34} \, Js$]
