Chapter 1, Problem 1FC

To determine

The correct option.

Answer to Problem 1FC

The correct option is (d) 4.

Explanation of Solution

In the head-tail arrangement of the vector diagram, the resultant vector $\left(\overrightarrow{R}\right)$ is drawn from the tail of the first vector $\left(\overrightarrow{A}\right)$ to the head of the second vector $\left(\overrightarrow{B}\right)$, for the convenience of the calculation of the magnitude of the resultant using the Pythagoras theorem or the expression for finding the resultant vector,

$R=\sqrt{{\left(A\right)}^2+{\left(B\right)}^2}$

Here,

A is the magnitude of the vector $\overrightarrow{A}$, and

B is the magnitude of the vector $\overrightarrow{\text{B}}$.

So, the correct option is (d) which the exact head-tail arrangement of the vectors.

Conclusion:

Thus, the correct option is (d) 4.
