If |A|=2 and |B|=4 and angle between then is `60^(@)` then |A-B|

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

Let vec(a) and vec(b) be two given vectors such that |vec(a)|=3, |vec(b)|=4 and the angle between them is 60^(@) . Find vec(a).vec(b) .

if vec(a) and vec(b) are having same magnitude and angle between them is 60^(@) and their scalar product is 1/2 , then |vec(a)| is ……………

Angle between vec(a) and vec(b) is 60^(@) then

Angle between vec(a) and vec(b) is 60^(@) then

Angle between vec(a) and vec(b) is 60^(@) then

If |vec a| = 4, |vec b| = 2, |vec c| = 6 and each of the angles between the vectors is 60^(o) then |vec a + vec b + vec c| =

If absa = 5, absb = 6 and the angle between a and b is 60^@ ,then a. b =
