A and B are two objects with masses 10 kg and 40 kg respectively. Then

Options

A. A has more inertia than B
B. B has more inertia than A
C. A and B have the same inertia
D. Neither A nor B has any inertia

Answer

To solve the problem of comparing the inertia of two objects A and B with masses 10 kg and 40 kg respectively, we can follow these steps:

### Step 1: Understand the Concept of Inertia
Inertia is the property of an object to resist changes in its state of motion. The greater the mass of an object, the greater its inertia. This means that heavier objects are harder to move or stop than lighter objects.

### Step 2: Identify the Masses of the Objects
- Mass of Object A (m_A) = 10 kg
- Mass of Object B (m_B) = 40 kg

### Step 3: Compare the Masses
Since inertia is directly proportional to mass, we can compare the masses of A and B:
- m_A (10 kg) is less than m_B (40 kg).

### Step 4: Conclude the Inertia Comparison
Since Object B has a greater mass than Object A, it will also have greater inertia. Therefore, we can conclude:
- Inertia of A < Inertia of B

### Step 5: Final Answer
Thus, the correct conclusion is that Object B has more inertia than Object A.
