Question

A force of 15 newton moves a body with an acceleration of 3 meter per second square it,s mass is
​

Answer 1

Given:-

☛Force = 15N

☛Acceleration = 3m/s

Find:-

☛Mass of the body-?

Solution:-

According to newton's second law of motion,

Force = mass × Acceleration

Put the given value in the formula we get,

$\bf{\implies 15= mass \times 3}$

$\bf{\implies \dfrac{15}{3} = mass}$

$\bf{\implies mass = 5}$

Therefore,Mass of the object is 5kg.

Answer 2

We are given that, magnitude of force exerted in a particle is 15 N. An acceleration is observed in it by 3 m/s².

Now we know,

$\boxed{F = m \ • \ a}$

⇒ $m = \frac{F}{a}$

⇒ m = (15 N)/(3 m/s²)

⇒ m = (15 kg m/s²)/(3 m/s²)

⇒ m = 5 kg (answer).

More:-

• $F \propto m$ ...(A)
• $m \propto \frac{1}{a}$ ...(B)
• $F \propto a$ ...(C)

Now, discuss about the equation A, B, and C now.
