Find `|veca-vecb|`, if two vectors `veca` and `vecb` are such that `|veca|=2,|vecb|=3` and `veca*vecb=4`.

Find the angle between two vectors veca and vecb such that : |veca|=sqrt2,|vecb|=2 and veca*vecb=sqrt6 .

Find the angle between two vectors veca and vecb such that : |veca|=sqrt3,|vecb|=2 and veca*vecb=sqrt6 .

The angle between the vectors veca and vecb such that |veca|=|vecb|=sqrt2 and veca*vecb=1 is :

If two vectors veca and vecb are such that : |veca|=2,|vecb|=1 and veca*vecb=1 , then find the value of (3veca-5vecb)*(2veca+7vecb) .

If two vectors veca and vecb are such that |\veca|=3,|\vecb|=2 and veca.vecb=4 then find the value of (3veca-4vecb).(2veca+5vecb) .

If veca=-vecb , is it true that |veca|=|vecb| ?

For two non-zero vectors veca and vecb , write when |veca+vecb|=|veca|+|vecb| holds.

Let the vectors veca and vecb be such that |veca| = 3 and |vecb| = sqrt2/3 , then vecaxxvecb is a unit vector, if the angle between veca and vecb is:
