Q 3
Question

Fig. 6.23a shows a boy lying horizontally, and Fig. 6.23b shows the boy standing vertically on a loose sand bed. In which case does the boy sink more in the sand? Give reasons.

Show answer Hide answer
Answer
The boy sinks more when standing vertically.

Explanation

  • His weight is the same in both cases.
  • Lying down spreads the weight over a large area, giving low pressure.
  • Standing puts the weight on the small area of his feet, giving high pressure.
  • Higher pressure makes him sink more, so he sinks more while standing.
Standing puts the weight on a small area, raising the pressure, so he sinks more.
← Back to concept: 6.1 Pressure
