Answer 1

Answer :

2000N/m

Explanation :

Force exerted by stone = 500N

Area occupied by stone = 25cm = 0.25m

Pressure exerted by stone =  $\frac{Force}{Area}$  = $\frac{500N}{0.25m}$  =  $\frac{50000N}{25m} = 2000N/m$

Answer 2

______________________

❥ Given :-

• Force = 500 N
• Area = 25 cm²

______________________

❥ We need to find :-

• Pressure exerted = ?

______________________

❥ Solution :-

As we know that

P = F/A

Where ,

• P → Pressure = ?
• F → Force = 500 N
• A → Area = 25 cm² = 0.0025

Substituting the values we have ,

⇒ P = 500 ÷ 0.0025

⇒ P = 200000 pa

Hence , pressure exerted = 200000 pascal

➵ P = F/A

➵ W = FS

➵ F = m × a

➵ v² - u² = 2as or 2gH

➵ S = ut + 1/2 at²

➵ v = u + at

Where ,

• P → pressure
• A → area
• F → force
• W → Work
• S → distance
• m → mass
• a → acceleration
• v → final velocity
• u → Initial velocity
• t → time taken
• g → acceleration due to gravity
• H → height
