Given `vec a=4hat i+5hat j -hat k,vec b =hat i-4hat j+5hat k`.If `|vec c|=21 and vec c` is perpendicular to `vec a and vec b` , find in component form the vector `vec c`.

Given vec (a) = 4 hat (i) + 5 hat (j) - hat (k), vec(b) = hat (i) - 4 hat (j) + 5 hat (k) If |vec (c ) | = 21 and vec(c ) is perpendicular to vec(a) and vec (b ) , find in component form the vector vec(c )

let vec a=hat i+hat j-hat k and vec b=hat i-hat j-hat k and vec c be a unit vector perpendicular to vec a and coplanarwith vec a and vec b then vec c is

if vec a = 2 hat i - hat j+ hat k, vec b =hat i+ hat j - 2 hat k and vec c =hat i+ 3hat j - hat k , find λ such that vec a is perpendicular to λ vec b+ vec c

If vec a= hat i+ hat j+ hat k , vec c= hat j- hat k , vec adot vec b=5 and vec ax vec b= vec c , then vec b is equal to

vec a=3hat i-hat j-4hat k,vec b=-2hat i+4hat j-3hat k and vec c=hat i+2hat j-hat k,f in d|3vec a-2vec b+4vec c|

If quad vec a=3hat i-hat j-4hat k,vec b=-2hat i+4hat j-3hat k and vec c=hat i+2hat j-hat k find |3vec a-2vec b+4vec c|

If vec a= hat i+ hat j , vec b= hat j+ hat k , vec c= hat k+ hat i find the unit vector in the direction of vec a+ vec b+ vec cdot

If vec a = hat i + hat j, vec b = hat i + hat k, vec c = hat k + hat i, a unit vector parallel to vec a + vec b + vec c

If vec A=hat i+hat j+hat k,vec B=4hat i+4hat j+4hat k and vec R=vec A+vec B then angle that vec R makes with vec A is

If vectors vec a=2 hat i+2 hat j+3 hat k ,\ vec b=- hat i+2 hat j+ hat k and vec c=3 hat i+ hat j are such that vec a+lambda\ vec b is perpendicular to vec c , then find the value of lambda
