Question

F1=40, F2=60. Find the magnitude and angle

Answer 1

Question:-

F1=40, F2=60. Find the magnitude and angle

Answer:-

Given that ,

Two forces F1 and F2= 5N

Angle £ = 60°

we know that , the resulant force is

|F| = |F1|+|F2|

|F| = √F1^2 + F2^2 +2F1F2cos£

|F| = √5^2 +5^2+2×5×5×1/2

|F| = √75

|F| = 8.66N

hence resultant force acting on the body is 8.66N.
