Answer:
[tex]\huge\boxed{\sf F= 350 \ N}[/tex]
Explanation:
Considering pivot as the central point,
Key:
- Torque = Force F × radius r
Anticlockwise torque = Clockwise torque
[tex]F_1r_1=F_2r_2[/tex]
Here,
- Anticlockwise force is F
- Clockwise force is 600 N
- [tex]r_1=70+50= 120 \ cm = 1.2 \ m[/tex]
- [tex]r_2=70 \ cm = 0.7 \ m[/tex]
Solution:
Substitute the givens in the above formula.
[tex]F(1.2)=600(0.7)\\\\F(1.2)=420\\\\Divide \ 1.2 \ to \ both \ sides\\\\F=420/1.2\\\\F= 350 \ N\\\\\rule[225]{225}{2}[/tex]
