Step-by-step explanation:
The equilibrant force is opposite and equal in the magnitude of the resultant force.
The magnitude of the resultant force can be calculated using the Pythagorean theorem as follows:
![\sqrt[]{10^2+6^2}=\sqrt[]{100+36}=\sqrt[]{136}=11.66\text{ N}](https://img.qammunity.org/2023/formulas/physics/college/v9ndxclkmy103ewgvliizo5g4jka3d6163.png)
Therefore, the resultant force is:
Now, the equilibrant force is opposite to this one. Then, the equilibrant force is
