In q-5 of ,NCERT-12,ex 10.2 "Find λ and μ if (2i+6j+27k)x(i+λj+μk)=0" Since the vector product is zero, the two vectors are parallel right? When vectors are parallel, their direction ratios are equal right? So is λ=6 and μ=27?

Dear student if vectors are parallel then their direction ratio are in constant proportion. Hence 2/1 = 6/lambda = 27/Mu lambda = 3Mu = 27/2
