Questions & Step-by-Step Solutions
A 10 kg object is hanging from a rope. What is the tension in the rope when the object is at rest?
Correct Answer: 100 N
Step 1: Identify the mass of the object. In this case, the mass is 10 kg.
Step 2: Understand that the object is hanging at rest, which means the forces acting on it are balanced.
Step 3: Recognize that the weight of the object (the force due to gravity) can be calculated using the formula: weight = mass * gravity.
Step 4: Use the value of gravity, which is approximately 10 m/s².
Step 5: Calculate the weight of the object: weight = 10 kg * 10 m/s² = 100 N.
Step 6: Since the object is at rest, the tension in the rope (T) must equal the weight of the object. Therefore, T = 100 N.
Weight and Tension – The weight of an object is the force due to gravity acting on it, and when the object is at rest, the tension in the rope must balance this weight.
