A man weighing 100 kg carriesa load of 10kg on his head. He jumps from a tower with the load on his head. What will be the weight of the load as experienced by the man?

Options

A. zero
B. 10kg
C. slightly more than 10 kg
D. 110 kg

Explanation

To solve the problem, we need to analyze the situation of the man and the load when he jumps from the tower.

### Step-by-Step Solution:

1. **Understanding the Situation**:
- The man has a weight of 100 kg and is carrying a load of 10 kg on his head.
- When he jumps from the tower, both the man and the load will be in free fall due to gravity.

2. **Weight Calculation**:
- The weight of the man can be calculated using the formula:
\[ \text{Weight} = \text{mass} \times g \]
where \( g \) is the acceleration due to gravity (approximately \( 9.81 \, \text{m/s}^2 \)).
- The weight of the man is:
\[ W_{\text{man}} = 100 \, \text{kg} \times 9.81 \, \text{m/s}^2 = 981 \, \text{N} \]
- The weight of the load is:
\[ W_{\text{load}} = 10 \, \text{kg} \times 9.81 \, \text{m/s}^2 = 98.1 \, \text{N} \]

3. **Free Fall Condition**:
- When the man jumps, both he and the load are falling under the influence of gravity.
- In free fall, all objects experience the same acceleration due to gravity, and there is no normal force acting on the load from the man's head.

4. **Normal Force**:
- The normal force is the force exerted by a surface to support the weight of an object resting on it. In this case, since both the man and the load are falling freely, there is no contact force acting between the man's head and the load.
- Therefore, the normal force (which is the force that would be felt as weight) is zero.

5. **Weight Experienced by the Man**:
- Since there is no normal force acting on the load while in free fall, the weight of the load as experienced by the man is:
\[ \text{Weight experienced by the man} = 0 \, \text{N} \]

### Final Answer:
The weight of the load as experienced by the man while in free fall is **0 N**.
