Lady_Fox [76]

Answer:2

Explanation:

Given

$m_2>m_1$

and $a_1$ and $a_2$ are the acceleration of 1 and 2

Suppose T is the Tension

then for block 2

$m_2g-T=m_2a$

$m_2(g-a)=T---1$

For block 1

$T-m_1g=m_1a$

$T=m_1(g+a)----2$

equate 1 and 2

$m_2(g-a)=m_1(g+a)$

$a=\frac{m_2-m_1}{m_1+m_2}$

where $a=a_1=a_2$

thus we can see that a is less than g

therefore $a_2 < g$
