Question

two equal forces are acting at apoint with an angle of 60 degree between them if the resultant force is equal to 40√3 N the magnitude of each force is​

Answer 1

Explanation:

Let equal forces

F1 = F2 = F newton

angle between the forces,

Theta= 60°

Resultant force, R=

40√3

Now,

R = √F1² +√F2² +√2F1F2Cos theta

Thus,

40√3 = √F²+√F²+√2Fcos60°

or F=40N
