To find the acceleration of the object, you can use Newton's second law of motion, which states that \( F = m \times a \), where \( F \) is the force applied, \( m \) is the mass of the object, and \( a \) is the acceleration.

Rearranging the equation to solve for acceleration gives:

\[ a = \frac{F}{m} \]

Using the values provided:

  • \( F = 10 , \text{N} \)
  • \( m = 2 , \text{kg} \)

Substituting these values into the equation:

\[ a = \frac{10 , \text{N}}{2 , \text{kg}} = 5 , \text{m/s}² \]

Therefore, the object's acceleration is 5 m/s².
