It `| vec a|=4\ and-3lt=lambdalt=2,` then write the range fo `lambda |vec a|dot`

It |vec a|=4 and -43<=lambda<=2, then write the range fo | lambda widehat a|

If |vec a| = 4 and -3 le lambda le 2 , then the range of |lambda vec a| is

If |vec a| = 4 and -3 le lambda le 2 then the range of |lambda vec a|

If | vec a X vec b|^2+| vec adot vec b|^2=400 and | vec a|=5, then write the value of | vec b|dot

If |vec(a)|=4 and -3 lek le2 , then the range of | k vec(a) | is

If |vec a| =4 and -3 le λ le 2 then the range of |λ vec a| is...........

If vec a and vec b are two vectors and lambda>0, then the least value of (1+lambda)|vec a|^(2)+(1+(1)/(lambda))|vec b|^(2) is

If |vec a| = 3, | vec b| = 4 , then the value of lambda for which vec a + lambda vec b is perpendicular to vec a = lambda vec b is

If | vec(a) | =3 and |vec(b) |=4 , then the value of lambda for which vec(a) + lambda vec(b) and vec(a) - lambda vec(b) are perpendicular is

If vec a\ a n d\ vec b are unit vectors then write the value of | vec axx vec b|^2+( vec adot vec b)^2dot
