Question
- A. 490 J
- B. 98 J
- C. 588 J
- D. 50 J
Answer
490 J
Explanation
The correct option is "490 J". 490 J is right because it directly matches Changes in energy: Apply the equation Ep = m x g x h when gravitational field strength is given.. The other options are less suitable because they change the required Physics relationship, confuse the relevant energy store or use a distractor that does not answer the question.
Common mistake
Common Mistake in Gravitational Potential Energy Calculation
Students often confuse the variables in the equation Ep = m x g x h, mistakenly using height in kilograms instead of metres.
Always ensure that height (h) is measured in metres when applying the gravitational potential energy equation.
