Question

two forcesof 3N and 4N are acting at a same point such that angle between them is 60degree.Find the resultant force and angle made by resulting force with 4N
​

Answer 1

Answer:

R = √ 3^2 + 4^2 + 2 (3) (4) cos 60°

= √ 9 + 16 + 24*1/2

= √9+ 16 + 12

= √37

Hence the resultant of two is √37.

And the angle made by resulting force with 4N is 30°
