Answer 1

`\huge\boxed{\sf F= 350 \ N}`

Step-by-step explanation:

Considering pivot as the central point,

Key:

• Torque = Force F × radius r

Anticlockwise torque = Clockwise torque

`F_1r_1=F_2r_2`

Here,

• Anticlockwise force is F
• Clockwise force is 600 N
• 
  `r_1=70+50= 120 \ cm = 1.2 \ m`
• 
  `r_2=70 \ cm = 0.7 \ m`

Solution:

Substitute the givens in the above formula.

`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}`
