To calculate the weight of an object, you can use the formula:
\[ \text{Weight} (W) = \text{mass} (m) \times \text{gravity} (g) \]
The standard acceleration due to gravity \( g \) is approximately \( 9.8 \, \text{m/s}^2 \).
For a mass of 20 kg:
\[ W = 20 \, \text{kg} \times 9.8 \, \text{m/s}^2 = 196 \, \text{N} \]
Therefore, the weight of a mass of 20 kg is approximately 196 N. Among your options, the closest answer is:
4. 196 N.
\[ \text{Weight} (W) = \text{mass} (m) \times \text{gravity} (g) \]
The standard acceleration due to gravity \( g \) is approximately \( 9.8 \, \text{m/s}^2 \).
For a mass of 20 kg:
\[ W = 20 \, \text{kg} \times 9.8 \, \text{m/s}^2 = 196 \, \text{N} \]
Therefore, the weight of a mass of 20 kg is approximately 196 N. Among your options, the closest answer is:
4. 196 N.
