Question

I'f the mass of the two substances 3 kg and 5 kg and 15 N force act on it find of their acceleration please tell it quick
​

Answer 1

$\huge{\pink{\underline{\underline{Answer:-}}}}$

Given:

Mass of two substance 3kg and 5kg

Force = 15 N

To find:

Ratio of acceleration = ?

Solution:

Force = Mass × Acceleration

F = ma

Let a1 and a2 be the acceleration on mass 3 kg and 5 kg

$\\ a = \dfrac{F}{m} \\ \\ a1 = \dfrac{15}{3} \\ \\ a2 = \dfrac{15}{5}$

$\\ a1 = \dfrac{15 }{3} \\ \\ = 5 \: \dfrac{m}{s {}^{2} }$

$\\ a2 = \dfrac{15}{5} \\ \\ = 3 \dfrac{m}{s {}^{2} }$

Required answer:

Therefore, acceleration of mass 3 kg is 5 m/s² and of 5 kg is 3 m/s²

Basic points:

# While solving such questions keep note on acceleration and force taken

# In block problems and pulley problems, we have to keep note on direction of acceleration and force

# Solve more such questions to get good hold on it
