If ( vec axx vec b)^2+( vec a.vec b)^2=144 and | vec a|=4, then find the value of | vec b|dot

Find | vec a|a n d\ | vec b| , if : ( vec a+ vec b)dot'( vec a- vec b)=12\ a n d\ | vec a|=2| vec b|

Find | vec a|a n d\ | vec b| , if : ( vec a+ vec b)dot'( vec a- vec b)=13\ a n d\ | vec a|=2| vec b|

If vec aa n d vec b are two vectors and angle between them is theta, then | vec axx vec b|^2+( vec adot vec b)^2=| vec a|^2| vec b|^2 | vec axx vec b|=( vec adot vec b),iftheta=pi//4 vec axx vec b=( vec adot vec b) hat n ,(w h e r e hat n is unit vector, ) if theta=pi//4 ( vec axx vec b)dot( vec a+ vec b)=0

The value of (axxb)^2 is | vec a|^2+| vec b|^2-( vec adot vec b)^2 b. | vec a|^2| vec b|^2-( vec adot vec b)^2 c. | vec a|^2+| vec b|^2-2( vec adot vec b)^2 d. | vec a|^2+| vec b|^2- vec adot vec b

If | vec axx vec b|=4,\ vec adot vec b =2,\ t h e n\ | vec a|^2| vec b|^2= 6 b. 2 c. 20 d. 8

if | vec(a) xx vec(b) |^(2) +| vec(a). vec(b)|^(2)= 144 and | vec(a) | =4 then |vec(b) | is equal to
