	1)	Which of the following is an example of inclined plane?
		Roller coasters Motor ramps All of the above Ladder

	2)	Why roller is used in the inclined plane experiment?
		To reduce the force due to friction. To increase the frictional force. To provide enough weight. None of these.

	3)	What is the weight of the body of mass m moving through an inclined plane placed at an angle θ?
		W= mg sinθ W= mg cosθ W= - mg sinθ W= mg

	4)	In which direction does the normal force of a body placed on a surface always act?
		Anti parallel to the surface Opposite to gravity Parallel to the surface Perpendicular to the surface

	5)	Which of the following statements is incorrect?
		The relation between downward force and angle of inclination is W = mg sinθ. There is no movement for a body moving on an inclined plane, in the direction of normal reaction The value of normal reaction is mg cosθ. The component of weight mg sinθ and normal reaction are opposite in direction.

	6)	What is the shape of the graph between W and sinθ ?
		Straight line Curve No fixed shape Parabola

	7)	What is meant by the angle of inclination?
		None of these Angle between the object and the inclined plane Angle made by the inclined plane with the horizontal. Angle between the object and the horizontal surface

	8)	The force required to move an object of mass m on an inclined plane is w. If the mass of the body is doubled, what will be the force (w’) required to pull the object on the same plane?(neglect force due to friction)
		w’ = w w’ = w/4 w’ = 0.5w w’ = 2w

	9)	What is the significance of the slope of the graph between W and sinθ?
		It gives the angle of inclination It gives the mass of the roller It gives the weight of the roller It gives the normal reaction.

	10)	Calculate the force required to move a body of mass 1 kg placed on a frictionless 10 degree inclined plane?
		0.17 N None of these 1.7 N 17 N
