Lifting of weight by vertical is more weightness than inclined?

I guess, balancing will be done as per the masses, since they are unknown, then one can not easily determine the result.
Considering them to be equal, then the value so obtained shall be dependent on angle.

In this same principal is used as that in lifting a bucket of water from any well. More the angle between ropes, lesser will be the force required to lift it. Hence less force means less acceleration of system.

Acceleration of this system is decrease with increase in angle of inclination.

It should be given either the two masses are equal or which one is heavier otherwise it will become impossible to say what will be the effect of increasing or decreasing the angle of inclination.

@Swanand hey as angle of inclination is been increased t angle between the ropes is decreased hence more force is required n more acceleration.

If m1sinA < m2 then the block will move downward on incline plan in this on increasing the angle acceleration will also increase. Vise-versa for other.

If you see the body with mass m1 is of friction and m2 isn't. When we increase the angle of inclination the acceleration of system tends to decrease because of that frictional force.

I think it depends on that which of the mass is heavier. If mass m1 is heavier then acc. will increase on increment of angle of inclination. If mass M2 is heavier than it will DECREASE. If both the masses are same then acc. will increase.

As we know that a = g*(m2-m1 sin(alpha)/(m2+m1).
As alpha value will increase putting the value of alpha in in numerator the value of acceleration will decrease.
