The third force that will cause the object to be in equilibrium will be 52 N pointing down. Option A is corect.
What is force?
Force is defined as the push or pull applied to the body. Sometimes it is used to change the shape, size, and direction of the body.
Force is defined as the product of mass and acceleration. Its unit is Newton.
Given data;
Force,F₁ = 78 N upwards(+ve)
Force F₂= -26 N downwards
Assume the downward
Let the third force is pointing down(+ve);
The third force will be the net force found as;
F+F₁-F₂=0
F = F₁ - F₂
F=78 -26 N
F = 52 N down
