Question

If a force of 12 N is applied to an object with a mass of 2 kg, what will be its acceleration? 0.17 m/s2 6 m/s2 24 m/s2 14 m/s2

Answer 1

The acceleration exerted by the object is $6 m s^{-2}$.

Answer: Option B

Explanation:

As per Newton’s second law of motion, the external force applied on an object will be equal to the product of mass (m) of the object and the acceleration exerted by the object. So the mathematical representation of Newton’s second law can be written as  

                           $\text {Force}= m\times \text {Acceleration}$

Thus as the force on the object is given as 12 N and mass of the object is given as 2 kg. So as per the formula

                           $12=2 k g \times \text { Acceleration }$

Thus the acceleration of the object will be

                           $\text {Acceleration}=\frac{12}{2}=6 \mathrm{ms}^{-2}$

Hence, the acceleration of the object with mass 2 kg and force applied of about 12 N is $6 m s^{-2}$

Answer 2

Answer

Correct Answer is

6 m/s^2

Explanation

in this question we have given

Force=12N

mass of oject=2kg

we know that

force= mass* acceleration

therefore,

acceleration=Force/mass.............(1)

Put values of mass and force in equation 1

$acceleration = 12/2\\\\acceleration=6m/s^2$
