`hata, hatb and hatc` are unit vectors. If the `hata +hatb = hatc`, them the magnitude of `hata -hatb` is :

Let hata, hatb and hatc be three unit vectors such that hata=hatb+(hatb xx hatc) , then the possible value(s) of |hata+hatb+hatc|^(2) can be :

Let hata, hatb and hatc be three unit vectors such that hata=hatb+(hatb xx hatc) , then the possible value(s) of |hata+hatb+hatc|^(2) can be :

If hata and hatb are two unit vectors inclined at an angle theta , then the value of |hata-hatb| is -

If hata, hatb, hatc are unit vectors such that hata+hatb+hatc=0 then find the value of hata.hatb+hatb.hatc+hatc.hata

If hata,hatb and hatc are three unit vectors such that hata + hatb + hatc is also a unit vector and theta_(1),theta_(2) and theta_(3) are angles between the vectors hata,hatb,hatb,hatc and hatc,hata, respectively m then among theta _(1),theta_(2)and theta_(3)

If hata,hatb and hatc are three unit vectors such that hata + hatb + hatc is also a unit vector and theta_(1),theta_(2) and theta_(3) are angles between the vectors hata,hatb,hatb,hatc and hatc,hata, respectively m then among theta _(1),theta_(2)and theta_(3)
