If `|overlinea|=3,|overlineb|=4 and |overline a + overline b|=5,` then `|overline a - overline b|` is equal to

overlineA xx overline B = overlineB xx overline A or not?

If |overline(a)|=5, |overline(b)|=3, |overline(c)|=4 and |overline(a)| is perpendicular to |overline(b)| and |overline(c)| such that the angle between |overline(b)| and |overline(c)| is (5pi)/(6) , then [[overline(a),overline(b), overline(c)]]=

If |overline(a)|=3,|overline(b)|=4 and the angle between overline(a) and overline (b) is 120^@ , then |4overline(a)+3overline(b)| is equal to

[[overline(a), overline(b), overline(a)timesoverline(b)]]=

IF overlinea+overlineb+overlinec=overline0,|overlinea|=3|overlineb|=5 and |overlinec|=7 , then find the between overline a and overlineb .

If overline(a), overline(b) and overline(c) are unit coplanar vectors, then [[2overline(a)-overline(b), 2overline(b)-overline(c), 2overline(c)-overline(a)]]=

For three vectors overline(p),overline(q) and overline ( r) , if overline( r) =3 overline(p)+4overline(q) and 2 overline( r) = overline(p) - 3overline(q) then

If overline(a) is perpendicular to overline(b) and overline(c), |overline(a)|=2, |overline(b)=3, |overline(c)|=4 and the angle between overline(b) and overline(c) is (2pi)/(3) , then |[[overline(a), overline(b), overline(c)]]|=

The volume of paralleloP1ped with vector overline(a)+2overline(b)+overline(c), overline(a)-overline(b) and overline(a)-overline(b)-overline(c) is equal to k[[overline(a), overline(b), overline(c)]] . Then k=
