Question

In the figure, a person is putting small packets of potatoes in bins A, B, or C. The bins are placed on tables lower than the packet table. Which of the statements is/are TRUE? \begin{center} \includegraphics[width=0.5\textwidth]{39.jpeg} \end{center}

• A. Lifting the bag from the table and placing it in bin B will be less effortful compared to lifting and placing it in bin C
• B. Lifting the bag from the table and placing it in bin A will be more effortful compared to sliding it in bin C
• C. Lifting the bag from the table and placing it in bin B will be less effortful than sliding it to bin C
• D. Sliding the bag from the table to bin C will be less effortful than lifting it and placing it in bin C

Hint:

When comparing effort, consider both vertical lifting work (force × height) and horizontal sliding (reduced effort). Gravity helps in sliding down.

Answer 1

The Correct Option is A, B, D

Step 1: Observe the setup.
- Table with packets is higher.
- Bins A, B, C are placed on lower tables.
- To put into A or B, one must lift packets.
- To put into C, one can simply slide packets down (gravity helps).
Step 2: Analyze each option.
(A) Bin B is at a higher position than C, so less vertical drop → less effort than lifting to C. Correct.
(B) Bin A is the farthest/higher than C. Sliding to C is easier. Correct.
(C) Lifting to B involves more effort than sliding to C. So statement is wrong (it claims less effort). Incorrect.
(D) Sliding to C is easier than lifting to C. Correct. Final Answer: \[ \boxed{\text{A, B, D}} \]
