Answer: As seen from above, a stubborn stump is pulled by

Step 1 of 2

Force is a vector, so it has both magnitude and direction.

In order to calculate the resultant net force, when two vectors are acting on an object at certain angles between them; we have to use the parallelogram law of vectors.

That is, if two forces are acting simultaneously on an object are represented in direction and magnitude by using two adjacent sides of the parallelogram, while the resultant force can be represented in direction and magnitude as the diagonal of the parallelogram.

As two applied forces are equal,

The resultant net force vector is given by,

\(\bar{R}=\sqrt{\bar{F}+\bar{F}+2 \overline{F F} \cos \theta}\)

Where \(\bar{R}\) is the resultant net force, \(\bar{F}\) is the applied force, \(\theta\) is the angle between the two applied forces.
