Answer:
[tex]F=57N[/tex]
Explanation:
Recall that in this case, friction is not taken into account. Thus, Using the free body diagram, according to Newton's second law, we have:
For the lighter block:
[tex]\sum F_x=T=m_1a[/tex]
For the heavier block:
[tex]\sum F_x=F-T=m_2a(1)[/tex]
The acceleration is the same for both blocks:
[tex]a=\frac{T}{m_1}(2)[/tex]
So, replacing (2) in (1):
[tex]F-T=m_2\frac{T}{m_1}\\F=T(1+\frac{m_2}{m_1})\\F=19N(1+\frac{24kg}{12kg})\\F=57N[/tex]
