Write two properties of vector addition.

Three forces given by vectors $2 \hat{i}+2 \hat{j}, 2 \hat{i}-2 \hat{j}$ and $-4 \hat{i}$ are acting together on a point object at rest. The object moves along the direction

Explain the parallelogram method for vector addition. Also explain that this is comparable to triangle method.

A particle is simultaneously acted by two forces equal to $4\, N$ and $3 \,N$. The net force on the particle is

Let the angle between two nonzero vectors $\overrightarrow A $ and $\overrightarrow B $ be $120^°$ and resultant be $\overrightarrow C $

In the cube of side $a$ shown in the figure, the vector from the central point of the face $ABOD$ to the central point of the face $BEFO$ will be
