[" 3."vec A+vec B=2hat i" and "vec A-vec B=4hat j" then what will be "],[" the angle between "vec A" and "vec B" ? "]

vec(A)+vec(B)=2hat(i) and vec(A)- vec(B)=4hat(j) then angle between vec(A) and vec(B) is ?

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)| = 2, |vec(b)| = 7 and vec(a) xx vec(b) = 3hat(i) + 2hat(j) + 6hat(k) , find the angle between vec(a) and vec(b) .

If |vec(a) | =2, | vec(b) |=7 and vec(a) xx vec(b) = 3 hat(i) + 2hat(j) +6 hat(k) , then the angle between vec(a) and vec(b) is

The sum and difference of two vectors vec A and vec B are , vec A+vec B=2hat i+6hat j+hat k and vec A-vec B=4hat i+2hat j-11hat k . Find the magnitude of each vector and their scalar product vec A.vec B .

If |vec(a)| = 2, |vec(b)|= 7 and (vec(a) xx vec(b))=(3 hat(i) + 2 hat(j) + 6 hat(k)), " find the angle between " vec(a) and vec(b).

If |vec(a)| = sqrt(2) , |vec(b)| = 7 and vec(a) xx vec(b) = 2 hat(i) + 6 hat(j) + 3 hat(k) . Find the angle between vec(a) and vec(b) .
