Question: A 10 kg object is hanging from a rope. What is the tension in the rope if the object is at rest? (2019)

Options:

Correct Answer: 100 N

Exam Year: 2019

Solution:

At rest, the tension in the rope equals the weight of the object. Weight = mg = 10 kg * 10 m/s² = 100 N.

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 and at rest, which means the forces acting on it are balanced.
Step 3: Recall that the weight of an object can be calculated using the formula: Weight = mass (m) * acceleration due to gravity (g).
Step 4: Use the value of acceleration due to 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 must equal the weight of the object. Therefore, the tension in the rope is 100 N.

Weight and Tension – The tension in a rope supporting a stationary object equals the weight of the object due to gravitational force.
