Question

Value of lambda ( b bar cross c bar) if b bar ,c bar are unit vectors a bar +3b bar b+5c bar =0 ,2(a bar cross b bar ) +3 (b bar cross c bar )-5(a bar cross c bar)= lambda( b bar cross cbar )and modulus of b bar +c bar =1

Answer 1

Step-by-step explanation:

0 ,2(a bar cross b bar ) +3 (b bar cross c bar )-5(a bar cross c bar)= lambda( b bar cross cbar )and modulus of b bar +c bar =1
