NEET Questions Solved


Plot a graph showing variation of de-Brogile wavelength λ. versus 1V,where V is accelerating potential for two particles A and B carrying same charge but of masses m1m2m1>m2. Which one of the two represents a particle of smaller mass and why?               (2)


As λ=h2mqv

As the  charge of two particles is same,therfore         12

λ1vα1m i.e.    slopeα1m

Hence,particle with lower massm2will have greater slope.12
