The dot product of u with itself is 24. what is the magnitude of u?

Step-by-step explanation:

We have been given that the dot product if u with itself is 24.

Now, we know that the dot product of vector a and b is given by

Here, is the angle between the vectors a and b.

We have to find the dot product of u with itself. Hence,

a = u

b = u

Thus, dot product is given by

Thus, the magnitude of u is
