" Q4: If "|vec a|=4" and "-3<=y<=2" ,then write the range of "| gammabar(a)|" ."

If |vec(a) | = 3, | vec(b) | =4 and | vec(a) xx vec(b) | = 10 , then | vec(a). vec(b) |^(2) is equal to

A parallelogram has two adjacent sides which represent the vectors 5vec p + 2 vec q and vec p - 3 vec q where |vec p| = 2 sqrt 2, | vec q|= 3 and vec p, vec q are inclined at an angle pi/4 . Then the length of the shorter diagonal is ______.

If |vec a|=3,|vec b|=4and the angle between aandb is 120^(@), then find the value of |4vec a+3vec b|

If |vec(a)| = 3, |vec(b) = 4 and |vec(a) + vec(b)| = 1 , then |vec(a) - vec(b)| =

Find | vec a- vec b|,\ if:| vec a|=3,\ | vec b|=4\ a n d\ vec adot vec b=1

If |vec(a) | = 3, |vec(b)|= 4 and |vec(a)- vec(b)|=5 , then what si the value of |vec(a) + vec(b)| =?

Statement-I: If |vec(a).vec(b)|= |vec(a) xx vec(b)| then (vec(a), vec(b))= (pi)/(4) or (3pi)/(4) Statement-II: If vec(a).vec(b)= |vec(a) xx vec(b)| then (vec(a), vec(b))= (pi)/(4) or (3pi)/(4) Which of the above two statements are true?

If |vec a|=3,|vec b|=4 then a value of lambda for which vec a+lambdavec b is perpendicular to vec a-lambdavec b is : (9)/(16) (b) (3)/(4) (c) (3)/(2) (d) (4)/(3)
