Solution

The correct option is D
300 N

Given: P = 3 kPa = 3000 Pa, A = 1000 cm² = $\frac{1000}{10000}$ = 0.1 m²

Now, we know that,

P = $\frac{F}{A}$

So, F = P $\times$ A

F = 3000 $\times$ 0.1 = 300 N

The correct option is D 300 N Given: P = 3 kPa = 3000 Pa, A = 1000 cm² = 100010000 = 0.1 m² Now, we know that, P = FA So, F = P× A F = 3000 × 0.1 = 300 N

The correct option is D
300 N

Given: P = 3 kPa = 3000 Pa, A = 1000 cm² = $\frac{1000}{10000}$ = 0.1 m²

Now, we know that,

P = $\frac{F}{A}$

So, F = P $\times$ A

F = 3000 $\times$ 0.1 = 300 N
