All forces in this problem act on an object along the same axis. Two forces have values -5N +10N respectively. What should be done to bring the system into mechanical equilibrium???
The sum of the forces have to equal zero.
F-5N+10N=0
To bring the system into mechanical equilibrium, the sum of all the forces acting on the object should be equal to zero. Since the forces act along the same axis, we can add their magnitudes to find the net force.
In this case, the two forces have magnitudes of -5N and +10N respectively. To bring the system into equilibrium, the net force should be zero.
To achieve this, we need to apply an additional force that balances out the existing forces. The magnitude of this balancing force would be the opposite of the sum of the other forces.
Since the sum of -5N and +10N is 5N, we need to apply a force of -5N to cancel out the net force.
Therefore, to bring the system into mechanical equilibrium, an additional force of -5N should be applied in the opposite direction of the other forces.
