The magnitude of a given vector with end points $ (4, -4, 0)$ and $(-2, -2, 0)$ must be
If $| A + B |=| A |+| B |$ the angle between $\overrightarrow A $and $\overrightarrow B $ is ....... $^o$
The resultant of $\overrightarrow P $ and $\overrightarrow Q $ is perpendicular to $\overrightarrow P $. What is the angle between $\overrightarrow P $ and $\overrightarrow Q $
Following sets of three forces act on a body. Whose resultant cannot be zero
Explain the parallelogram method for vector addition. Also explain that this is comparable to triangle method.
