If a vector `vecA=2hati=2hatj+3hatk,` and `vecB=3hati=6hatj+nhatk`, are perpendicular to eachother tehn the value of 'n' is

Show that vectors vecA= 3hati+ hatj+ hatk and vecB= hati+ 2hatj- 5hatk are perpendicular to each other.

If the vectors 2 hati +2 hatj - hatk and 3 hati - 6hatj +nhatk are mutually perpendicular, find the value of n ?

If the vectors 2 hati +2 hatj - hatk and 3 hati - 6hatj +nhatk are mutually perpendicular, find the value of n ?

If the vectors 2hati+2hatj-hatk " and " 3hati-6hatj+nhatk are mutually perpendicular, find the value of n?

If veca=2hati+2hatj+3hatk, vecb=-hati+2hatj +k and vecc=3hati+hatj such that veca+lamdavecb is perpendicular to vector c then the find the value of lamda.

If the vectors veca=hati+hatj+hatk,vecb=2hati-hatj+hatk and vecc=khati-2hatj+3hatk are coplaner then find the value of k.

For what value of lamda are the vectors veca=2hati+lamda hatj+hatk and vecb=hati-2hatj+3hatk perpendicular to each other ?
