Write down the components of a vector using the three unit vectors ?

The component of a vector is

Define unit vector.

Let vec(AB) be a vector in two dimensional plane with magnitude 4 units. And making an anle of 60^0 with x-axis, and lying in first quadrant. Find the components of vec(AB) in terms of unit vectors hati and hatj . so verify that calculation of components is correct.

The sum of these three vectors is :

The magnitude of the x-component of vector vec(A) is 3 and the magnitude of vector vec(A) is 5. What is the magnitude of the y-component of vector vec(A) ?

If three vector along coordinate axis represent the adjacent sides of a cube of length b, then the unit vector along its diaonal passing thourth the origin will be

What is a unit vector?

The position vectors of the vertices A, B and C of a triangle are three unit vectors veca, vecb and vecc respectively. A vector vecd is such that vecd.hata =vecd. Hatb=vecd.hatc and vecd= lambda (hatb + hatc) . Then triangle ABC is
