What is the wavelength associated with a particle of mass 0.1g moving with a speed of {\sf 1×10^5\:cm/s} {\sf [ h = 6.6×10^{-27}\:erg\:sec]}

\huge\underline{\underline{\bf \green{Solution-}}}

\large\underline{\underline{\sf Given:}}

  • Mass ( m ) = 0.1 g \implies{\dfrac{0.1}{1000}\:\:\implies\:\:\:10^{-4}\:kg}
  • Speed ( v ) = {\sf 1×10^5\:cm/s}
  • h = {\sf 6.6×10^{27}\:erg\:sec}

\large\underline{\underline{\sf To\:Find:}}

  • Wavelength {\sf (\lambda)}

\large{\boxed{\bf \blue{\lambda = \dfrac{h}{mv} }}}

\implies{\sf \dfrac{6.6×10^{-27}}{10^{-4}×10^5} }

\implies{\sf \dfrac{6.6×10^{-27}}{10}}

\implies{\bf \red{\lambda =6.6×10^{-28}\:cm }}

\huge\underline{\underline{\bf \green{Answer-}}}

Wavelength of the particle is {\bf \red{(\lambda)=6.6×10^{-28}}}
