**Relevant eqs:-**

F = ma

**Attempt at solution:-**

The equations I've gotten so far:-

1) N1sin(theta) = m2a

2) m1gsin(theta) = m1a1

3) m1gcos(theta) - N1 = m1a2

So far, 3 eqs, 4 unknowns.

For the 4th eq, I did a2sin(theta) = a i.e the horizontal component of a2 = a.

However, this is wrong. The correct last eq is a2 = asin(theta) i.e. the component of a perpendicular to the plane = a2. Why is my answer wrong? I don't see the difference in relating them in these different ways.

*Note:- I've verified for a fact that my answer is incorrect(a2sin(theta) = a)*
