The direction cosines of a vector vec(A) are cos alpha = (4)/(5sqrt(2)), cos beta = (1)/(sqrt(2)) and cos gamma = (3)/(5sqrt(2)), then the vector vec(A) is

The direction cosines of a vector vec(A) are cos alpha = (4)/(5sqrt(2)

1.	The direction cosines of a vector vec(A) are cos alpha = (4)/(5sqrt(2)), cos beta = (1)/(sqrt(2)) and cos gamma = (3)/(5sqrt(2)), then the vector vec(A) is
Answer» `4hat(i) + hat(J) + 3hat(K)` `4hat(i) + 5hat(j) + 3hat(k)` `4hat(i) - 5hat(j) - 3hat(k)` `hat(i) + hat(j) -hat(k)` ANSWER :B
