Question

A force of 10 N acts on an object with a mass of 10 kg. What is its acceleration? A. 1 m/s2 B. 10 m/s2 C. 2 m/s2 D. 5 m/s2

Answer 1

The acceleration exerted by the object of mass 10 kg is
`\mathbf{1} m / \boldsymbol{s}^(2)`

Answer: Option A

Step-by-step explanation:

According to Newton’s second law of motion, any external force acting on a body will be directly proportional to the mass of the body as well as acceleration exerted by the body. So, the net external force acting on any object will be equal to the product of mass of the object with acceleration exerted by the object. Thus,

`Force = Mass * Acceleration`

So,

`Acceleration=\frac{\text {Force}}{\text {Mass}}`

As the force acting on the object is stated as 10 N and the mass of the object is given as 10 kg, then the acceleration will be

`Acceleration =\frac{10 \mathrm{N}}{10 \mathrm{kg}}=1 \mathrm{m} / \mathrm{s}^(2)`

So, the acceleration exerted by the object of mass 10 kg is
`\mathbf{1} m / \boldsymbol{s}^(2)`
