If `vec A=(hat i+2hat j+5hat k)` and `vec B=(hat i+5hat j+7hat k)`, then the projection of `vec A` on `vec B` would be

If vec a=2hat i+hat j+hat k,vec b=3hat i-4hat j+2hat k and vec c=hat i-2hat j+2hat k then the projection of vec a+vec b is

If vec(A)=2hat(i)+3hat(j)-hat(k) and vec(B)=-hat(i)+3hat(j)+4hat(k) , then find the projection of vec(A) on vec(B) .

If vec a=hat i-hat j and vec b=-hat j+hat k find the projection of vec a on vec b

If vec(a) = 2hat(i) + hat(j) - hat(k) and vec(b) = hat(i) - hat(k) , then projection of vec(a) on vec(b) will be :

If vec A =4 hat I + 6 hat j -3 hat k and vec B =- 2 hat I -5 hat j + 7 hat k , find the angle between vec A and vec B .

If vec(a) = 2hat(i) + hat(j) + 2hat(k), vec(b) = 5hat(i) - 3hat(j) + hat(k) , then projection of vec(a) on vec(b) is

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

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

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

If vec a=hat i-2hat j+hat k,vec b=2hat i+hat j-hat k and vec C=3hat i+5hat j+2hat k then find the value of vec a xx(vec b xxvec c)
