" Let "vec a=3hat i+2hat j+xhat k" and "vec b=hat i-hat j+hat k," for some real "x." Then "|vec a timesvec b|=r" is possible if ":

Let vec a=3hat i+2hat j+xhat k and vec b=hat i-hat j+widehat K Some real x. Then |vec a xxvec b|=r is possible if:

If vec a = hat i + 2 hat j - 3 hat k and vec b = 3 hat i - hat j + 2 hat k , then vec a + vec b and vec a - vec b are

Taking vec a= 2 hat i-3 hat j- hat k and vec b=hat i+4 hat j-2 hat k , verify that vec a * vec b = vec b*vec a .

Let vec a=5 hat i- hat j+7 hat k and vec b= hat i- hat j+lambda hat k . Find lambda such that vec a+ vec b is orthogonal to vec a- vec bdot

Let vec a=3 hat i+2 hat j+hat k,vec b=2 hat i-hat j+3 hat k and vec c be a vector such that (vec a+vec b)timesvec c=2(vec a timesvec b)+24 hat j-6 hat k and (vec a-vec b+hat i)*vec c=-3 .Then |vec c|^(2) is equal to:

vec a = (hat i + hat j + hat k), vec a * vec b = 1 and vec a xxvec b = hat j-hat k. Then vec b is

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 = 5 hat i - hat j - 3 hat k and vec b = hat i + 3 hat j - 5 hat k , then show that the vectors vec a + vec b and vec a - vec b are orthogonal

If vec a=5 hat i-hat j-3 hat k and vec b=hat i+3 hat j -5 hat k , then show that the vecctors vec a+vec b and vec a-vec b are perpendicular.
