Answer:
the magnitude of the resultant of two forces is 25 N.
Step-by-step explanation:
Given;
first force, F₁ = 20 N
second force, F₂ = 15 N
the angle between the two forces, θ = 90⁰
The resultant of these two forces is obtained by applying Pythagoras theorem;
R² = F₁² + F²
Where;
R is the resultant force
R² = 20² + 15²
R² = 625
R = √625
R = 25 N
Therefore, the magnitude of the resultant of two forces is 25 N.
