Question

a force of 5 Newton gives a mass M1 and acceleration of 10 metre per second square and a mass M2 an acceleration of 20 metre per second square what acceleration would it give if both the masses with tied together​

Answer 1

Answer:

this is the answer according to NEWTON LAWS OF MOTION CHAPTER ncert class 12th

Answer 2

$\huge \bold \green{Answer:- }$

$\bf \: For \: \: mass \: m_1: \: F = \: m_1a_1$

$\bf\therefore \: \: m_1 \: = \: \frac{F}{a_1} = \frac{5}{10} = \: 0.5 \: kg \:$

$\bf \: For \: \: mass \: m_2 \: : \: F = \: m_2a_2$

$\bf\therefore \: \: m_2 \: = \: \frac{F}{a_2} = \frac{5}{20} = \: 0.25 \: kg \:$

$\bf \: To \: combined \: mass \: = m_1 \: + m_2 \: = \: 0.5 \: kg \: + \: 0.25 \: \: kg \: = \: 0.75 \: kg \:$

$\bf \: For \: combined mass \: : F = (m_1 + m_2)a$

$\bf \: \therefore \: a \: = \frac{F }{ m_1 \: + \:m_2 \: } = \: \frac{5}{0.75} = 66.7 \:ms¯²$
