Let bara.barb and barc are three unit vectors such that |bara+barb+barc|=sqrt3 such that (bara times barb).(barb times barc)+(barb times barc).(barc times bara)+(barc times bara).(bara.barb)=lamda

Answer»

the maximum VALUE of `LAMDA` is 2
when `lamda` is maximum then the volume of parallelepiped determined by `BARA.barb and barc` is `sqrt3`
when `lamda` is maximum then the value of `|(2bara+3barb+4barc).(bara TIMES barb times 5barb times barc+5barc times bara)|` is 32.
None of these
