How much tension is in a rope that holds up a 20-N bag of apples at rest?
Tension in the rope.
Answer to Problem 7A
Tension in the rope is
Explanation of Solution
Given:
Weight of bag of apples,
Formula Used:
For mechanical equilibrium, summation of all forces is zero, that is
Calculation:
The weight of bag will be downward and tension in rope will be upward.
Let, tension in rope is T
Since, the bag is in mechanical equilibrium so,
Upward force = Downward force
Conclusion:
Therefore, the tension in rope is
