The magnitude of the resultant force is 10.17N

Given : Two forces 5N and 6N act at a point on a body. The resultant when they act at 45 degrees.

To find : The magnitude of the resultant of two forces.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the value of the magnitude of resultant force)

Here, we will be using the following formula.

Magnitude of resultant force = ( + + 2PQcosθ )

Here,

  • P = One force
  • Q = Another force
  • θ = Angle between force P and Q

So,

By putting the available data, we get :

Resultant force = √[(5)²+(6)²+(2×5×6×cos45°)] = 10.17 N (approx)

(This will be considered as the final result.)

Hence, the magnitude of the resultant force is 10.17N
