Two weights A and B of 5kg and 10kg respectively (not in contact) are sliding down the inclined plane at an angle of 30 degrees from the horizontal. What is the acceleration with which the weights will slide down?

Dear student,

It need to be clearly mentioned if the surface is frictionless or not. However if the surface is frictionless, the acceleration of both the blocks will be.
This is independent of the mass of body( as long as surface is smooth only).

Regards,
