Answer:
Added
Explanation:
Force is a vector quantity. It follows vector law of addition.
If two forces act in the same direction, the angle between the two force vectors become zero and thus the resultant force turns out to be the algebraic addition of the applied individual forces.
Feq = √(F1²+F2²+2F1.F2.cos0) = √(F1+F2)² = F1+F2.
