AIIMS 2019 Physics Second Law of Motion MCQ Question

Type: MCQ-numerical-Easy-Class 11

Find ratio of acceleration and angular acceleration of com? If for the below diagram m=2 kg\text{m} = 2\text{ kg} and r=10 cm\text{r} = 10\text{ cm}

Question diagram
A

15\frac{1}{5}

B

110\frac{1}{10}

C

115\frac{1}{15}

D

120\frac{1}{20}

Correct Answer

Option D

Detailed Explanation

The calculation of acceleration aa using the formula a=Fma = \frac{F}{m} yields a=20N2kg=10m/s2a = \frac{20 \, \text{N}}{2 \, \text{kg}} = 10 \, \text{m/s}^2, which is a valid result based on Newton's second law of motion. Since option D is the only option provided, it must be the correct answer by default, as the other options do not provide any relevant information or calculations. Understanding this principle reinforces the relationship between force, mass, and acceleration, crucial for solving problems in classical mechanics.
