Question

What will happen if you place a cup on an inclined surface in space?

• A. It will slide along the surface
• B. It will rise up vertically
• C. It will rise perpendicular to the plane of the inclined surface
• D. It will remain stationary at its position

Answer 1

Answer: (C)

It will rise perpendicular to the plane of the inclined surface

As there is no gravity is space, thus no gravitational force acts on the cup kept in space. The only force acting on the cup placed on the inclined surface is the normal reaction exerted by the inclined surface (perpendicular to the plane of inclined surface) which makes the cup to rise in the direction perpendicular to the plane of inclined surface.
