if `veca=2i+2j+3k , vecb=-i+2j+k` and `vcec=3i+j` are such that `veca+lambdavecb` is perpendicular `vecc` then find the value of `lambda`

If veca=2 hat i+2 hat j+3 hat k , vecb=- hat i+2 hat j+ hat k and vecc=3 hat i+ hat j are such that veca+lambda vecb is perpendicular to vecc , then find the value of lambda .

If vec a = i + 2j+3k, vec b = i-2j+k, vec c = 4i+3j-2k and vec a + lambda vec b is perpendicular to vec c then lambda =

If veca=3i-j-5k and vecb=i-5j+3k Show that veca+vecb and veca-vecb are perpendicular.

If veca=i-2j+3k, vecb=2i+3j-5k , prove that vecaandvecaxxvecb are perpendicular.

Let veca = 2i + j+k, vecb = i+ 2j -k and a unit vector vecc be coplanar. If vecc is pependicular to veca .Find vecc .

Let veca = 2i + j+k, vecb = i+ 2j -k and a unit vector vecc be coplanar. If vecc is pependicular to veca . Then vecc is

Let veca = 2i + j+k, vecb = i+ 2j -k and a unit vector vecc be coplanar. If vecc is pependicular to veca . Then vecc is

Let veca = 2i + j+k, vecb = i+ 2j -k and a unit vector vecc be coplanar. If vecc is pependicular to veca . Then vecc is

If veca=i-2j+3k , vecb=2i+3j-4k and vecc=i-3j+5k ,then check whether veca , vecb , vecc are coplanar.
