In the figure shown, A&B are free to move. All the surfaces are smooth. ( $0 < θ < 9 0^{\circ}$ )

Answer:

A, D

Solution:

Force along inclined plane

$= m_{A} g sin α + m_{A} a cos α$

acc. along inclined plane

$= g sin α + a cos α$

So,

$a_{A} > g sin α$

$N = m_{A} g cos α - m_{A} asin α$

$N < m_{A} g cos α$
