Suppose you have two forces `overset(rarr)F` and `overset(rarr)F` how would you combine them in order to have resultant force of magnitudes (a) zero , (b) `2 overset(rarr)F` and (c ) `overset(rarr)F` ?

Explanation

To solve the problem of combining two forces \( \vec{F} \) and \( \vec{F} \) to achieve different resultant magnitudes, we will analyze each case step by step.

### Given:
Two forces \( \vec{F} \) and \( \vec{F} \).

### Resultant Force Formula:
The resultant force \( \vec{R} \) when combining two forces can be expressed as:
\[
