Question

two forces 5n and 7n are acting on a body from opposite directions. calculate the magnitude and find the direction of the resultant force.​

Answer 1

Explanation:

f(x)=x

2

−3x+1

f(2α)=(2α)

2

−3(2α)+1=4α

2

−6α+1

f(2α)=2f(α)

∴4α

2

−6α+1=2(α

2

−3α+1)

4α

2

−6α+1=2α

2

−bα+2

4α

2

+1=2α

2

+2

2α

2

=1 α=±
