Question

A man presses more weight on earth at

• A. Sitting Position
• B. Standing Position
• C. Lying Position
• D. None

Answer 1

The correct option is B

Standing Position

Explanation of Correct Option:

Option B: Standing Position

1. The pressure exerted by a person on the earth's surface can be defined as the ratio of the force (weight of the person) exerted by him and the surface area he covers.
2. It can be written as $PressureexertedbyapersononEarth=\frac{Weightoftheperson}{Surfaceareathepersoncovers}$.
3. Therefore, pressure is inversely proportional to the area.
4. The area covered by a person is the least when he is standing, so the pressure exerted by the weight of a person will be the most in this case.

Explanation of Incorrect Option:

Option A:

The area covered by a person is more when he is sitting rather than standing, so the pressure exerted by the weight of a person will not be the highest in this case.

Option C:

The area covered by a person is most when he is lying, so the pressure exerted by the weight of a person will be the least in this case.

Option D:

It cannot be “none”, since option B is correct.

Hence, the correct option is option B.
