What is the magnitude of the resultant of two forces 20 Newton and 15 Newton at 90 degrees to each other

Respuesta :

Answer:

the magnitude of the resultant of two forces is 25 N.

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.
