Question

If a 1-megaton nuclear weapon is exploded at ground level, the peak overpressure (that is, the pressure increase above normal atmospheric pressure) will be 0.2 atm at a distance of 6 km. Atmospheric pressure is 1.013 × 105 Pa. What force due to such an explosion will be exerted on the side of a house with dimensions 2.9 m × 11 m? Answer in units of N.

Answer 1

The force exerted on the side of the house is due to the given explosion.

From the formula of pressure,

Where,

- pressure = 0.2 atm × 1.013×10⁵ Pa =

- Force = ?

- area = 3.89 m × 22.6 m =

So,

Put the values in the formula,

Therefore, the force exerted on the side of the house is due to the given explosion.
