Question

A force of \( 10 \, \text{N} \) acts on a body of mass \( 2 \, \text{kg} \). What is the acceleration of the body?

• A. \( 5 \, \text{m/s}^2 \)
• B. \( 2 \, \text{m/s}^2 \)
• C. \( 4 \, \text{m/s}^2 \)
• D. \( 1 \, \text{m/s}^2 \)

Hint:

Remember: According to Newton's second law, acceleration is directly proportional to the force and inversely proportional to the mass: \( a = \frac{F}{m} \).

Answer 1

The Correct Option is A

Step 1: Apply Newton's Second Law of Motion
Newton's second law of motion is defined as:\[F = ma\]
In this equation:
- \( F \) represents force,
- \( m \) represents mass,
- \( a \) represents acceleration.
Step 2: Isolate acceleration in the formula
Given values are:
- Force \( F = 10 \, \text{N} \),
- Mass \( m = 2 \, \text{kg} \).
To find acceleration, rearrange the equation:\[a = \frac{F}{m} = \frac{10}{2} = 5 \, \text{m/s}^2\]Answer: The body's acceleration is \( 5 \, \text{m/s}^2 \). The correct option is (1).
