To Choose: The correct option.
Answer to Problem 7STP
Option (D)
Explanation of Solution
Given:
Mass of a child,
Mass of the tire,
Formula used:
Newton’s second law:
Where,
Calculation:
Let the tension in the rope be
Tension in the rope would be in upward direction while the weight of the child and tire would be in downward direction.
Since, there is no acceleration, therefore net force acting on child and tire would be zero.
i.e.
Plugging in the given values:
Conclusion:
Tension in the rope:
