Homework Answers
Since the incline is friction less hence the plane is not applying any force on the block in parallel direction to the plane. But block has weight and hence net force on block will be its weight which always act. The normal force means normal reaction on the block is R which is mg cos (25)
If we compare these two forces means Net force (weight) and reaction force then we can conclude that the net force on the block is greater.
Diagram is attached here to show the directions.
