Question

find the resultant of two unequal forces acting at right angles to each other​

Answer 1

Explanation:

let forces be F1 and F2 respectively

as given F1 is not equals to F2

given they are perpendicular so angle between them is 90 degrees

formula of resultant of 2 force vectors

resultant = √(f1^2+F2^2+2.F1F2 cos theta)

theta is 90

resultant is √(f1^2+f2^2+2.f1.f2 *0)

so resultant is √f1^2+f2^2

Answer 2

Answer:

Let both the equal forces be [math]F[/math]

The resultant will be

[math]= √(F² + F² + 2F.F.cos(θ))[/math] (θis the angle between the forces)

[math]=√(2F² + 0)[/math] (cos(90) is 0)

[math]=√2.F[/math]

[math]=> √2.F = 1414[/math]

[math]=> F = 1.414*1000/√2[/math]

[math]=> F = 1000N[/math]
