IF `|veca|=sqrt(3), |vecb|=2 and |veca-vecb|=3` find the angle between `veca and vecb`.

If veca and vecb are two such that |veca|=5, |vecb|=4 and |veca.vecb|=10 , find the angle between veca and vecb and hence find |vecaxxvecb|

If veca and vecb asre two vectors such that |veca|=2, |vecb| = 7 and vecaxxvecb=3hati+6hatk find the angle between veca and vecb

If veca, vecb and vecc are such that [veca \ vecb \ vecc] =1, vecc= lambda (veca xx vecb) , angle between vecc and vecb is 2pi//3 , |veca|=sqrt2, |vecb|=sqrt3 and |vecc|=1/sqrt3 then the angle between veca and vecb is

If veca . vecb =ab then the angle between veca and vecb is

If |veca|+|vecb|=|vecc|and veca+vecb=vecc then find the angle between veca and vecb .

If veca,vecb are two unit vectors such that |veca + vecb| = 2sqrt3 and |veca -vecb|=6 then the angle between veca and vecb , is

If veca +vecb +vecc =vec0, |veca| =3 , |vecb|=5 and |vecc| =7 , then the angle between veca and vecb is

If |veca|=2,|vecb|=7 and (vecaxxvecb)=3hati+2hatj+6hatk find the angle between veca and vecb

If veca+vecb+vecc=0,|veca|=3,|vecb|=5,|vecc|=7 find the angle between veca and vecb

If veca +vecb +vecc=0, |veca|=3,|vecb|=5, |vecc|=7 , then find the angle between veca and vecb .
