Question

a scenario where two people are sitting on a see - saw is modeled here. assuming both people are at equal distances from the pivot point, which statements below would result in the unbalanced forces shown above? select all that apply. a person a has a force of 70 n and person b has a force of 80 n. b person a has a force of 80 n and person b has a force of 70 n. c person a has a force of 75 n and person b has a force of 75 n. d person a has a force of 50 n and person b has a force of 40 n. e person a has a force of 50 n and person b has a force of 70 n.

Explanation:

Step1: Recall balance - force concept

For a seesaw with equal - distance from pivot, more force on one side causes imbalance. The side with greater force will go down.

Step2: Analyze each option

• Option A: Person A (70 N) and Person B (80 N), Person B has more force, so Person B's side should go down, not Person A's as shown in the figure.
• Option B: Person A (80 N) and Person B (70 N), Person A has more force, which can cause the imbalance as shown (Person A's side going down).
• Option C: Person A (75 N) and Person B (75 N), equal forces result in balance, not imbalance.
• Option D: Person A (50 N) and Person B (40 N), Person A has more force, which can cause the imbalance as shown (Person A's side going down).
• Option E: Person A (50 N) and Person B (70 N), Person B has more force, so Person B's side should go down, not Person A's as shown in the figure.

Answer:

B. Person A has a force of 80 N and person B has a force of 70 N.
D. Person A has a force of 50 N and person B has a force of 40 N.
