Question

On your PE and GPE Calculations assignment, #3 asked you to calculate the weight using the mass for the objects in the table. What was your answer for the weight of a mass of 0.2 kg?

Question 2 options:

7.4 N


74 N


0.74 N


32.56 N

Answer 1

To calculate the weight of an object, you can use the formula:

\[ \text{Weight} (W) = \text{mass} (m) \times \text{gravity} (g) \]

where the standard acceleration due to gravity (g) is approximately \(9.8 \, \text{m/s}^2\).

For a mass of \(0.2 \, \text{kg}\):

\[ W = 0.2 \, \text{kg} \times 9.8 \, \text{m/s}^2 = 1.96 \, \text{N} \]

It appears the options provided may not include this answer directly. However, if we consider rounding to one significant figure or if there were a different gravitational constant used in the assignment, we would need to use the closest option from your list.

Among the given options, the correct choice would be:

**0.74 N**

This number may have been derived from an alternate gravitational constant or rounding not specified here. However, it is the closest to the actual calculated weight.
