Question

two unlike forces (parallel) of 10 N and 25 N act at a distance of 12 cm from each other. Find the pont about which the body will balance.​

Answer 1

Answer:

Hello mate

Explanation:

Let the balance be at x cm from the 25N force.

Anti-clockwise movement = 10 (12 - x)  

Applying principle of moments,

⇒ 10 (12 - x) = 25x

⇒ 120 - 10x = 25x  

⇒ 35x = 120

⇒ x = 120/35

= 3.43 cm.

∴ The body balances at the 3.43 cm mark.

hope this helps u

Answer 2

Answer:

Let the balance be at x cm from the 25N force.

Anti-clockwise movement = 10 (12 - x)  

Applying principle of moments,  

⇒ 10 (12 - x) = 25x

 120 - 10x = 25x  

⇒ 35x = 120

⇒ x = 120/35

= 3.43 cm.

∴ The body balances at the 3.43 cm mark.
