Question

Force of 2 Newton acts on a body
of mass 0.5 kg then acceleration
produced in the body is
a)l
b)2
c)4
d) 6​

Answer 1

Answer:

6

Explanation:

Answer 2

Answer:

Provided that:

• Force = 2 Newton
• Mass = 0.5 kg

To calculate:

• The acceleration

Solution:

• The acceleration = 4 m/s²

Knowledge required:

• SI unit of mass = kg
• SI unit of acceleration = m/s sq.
• SI unit of force = Newton (N)

Using concept:

• Second law of motion that tell us about the formula to calculate the force.

Using formula:

• ${\small{\underline{\boxed{\pmb{\sf{F \: = ma}}}}}}$

Where, F denotes force, m denotes mass and a denotes acceleration.

Required solution:

$:\implies \sf Force \: = Mass \times Acceleration \\ \\ :\implies \sf F \: = m \times a \\ \\ :\implies \sf F \: = ma \\ \\ :\implies \sf 2 \: = 0.5(a) \\ \\ :\implies \sf \dfrac{2}{0.5} = a \\ \\ :\implies \sf \dfrac{20}{5} = a \\ \\ :\implies \sf 4 = a \\ \\ :\implies \sf a \: = 4 \: mps^{-2} \\ \\ :\implies \sf Acceleration \: = 4 \: mps^{-2}$

• Therefore, acceleration = 4 metre per second sq. Henceforth, option c) is correct.

Additional information:

Force: Push and pull on any object is known as force. Force can be also define as the push or pull on an object that have mass that cause the change in velocity of the object.

Effects of force:

1. Force can move a stationary object.

2. Force can stop a moving object.

3. Force can make the change in the size of the object.

4. Force can make the change in the shape of the object.

5. Force can make the change in the speed of the object.

Types of force: There are two types of force that are balanced force and unbalanced force.
