In given graph if V_(02)gtV_(01) then…….

Answer»

`lambda_(1)=sqrt(lambda_(2))`
`lambda_(1)ltlambda_(2)`
`lambda_(1)gtlambda_(2)`
`lambda_(1)gtlambda_(2)`

Solution :`V_(0)=((h)/(e ))V-(phi_(0))/(e )` and
From GRAPH `(V_(0))_(2)gt(V_(0))_(1)`
`therefore ((h)/(e ))V_(2)-(phi_(0))/(e )gt((h)/(e ))V_(1)-(phi_(0))/(e )`
`therefore V_(2)gtV_(1)[V_(0)=(hv)/(e )-(phi_(0))/(e )]`
`therefore lambda_(2)lt lambda_(1) [because LAMBDA prop(1)/(V)]`
`therefore lambda_(1)gtlambda_(2)`
