Question

give one example of dot product of vector .give si unit​

Answer 1

Explanation:

Dot Product of a vector is given by a.b=lal lbl cost where a and b are vectors, lal, lbl are the magnitudes and t is the angle between the two given vectors .

So the dot product of a vector with its own vector would give the magnitude of the vector as the angle between the two vectors is 0 (so cos0=1) and magnitude of unit vector is 1

Answer 2

Explanation:

wrok is equal to force and displacement
