Passage III
An elevated inclined plane makes, an angle, θ, with a floor. Points A and B on the inclined plane are 0.50 m apart. Point B is at a height H above the floor (see Figure 1).
A solid metal sphere is released from rest at Point A and travels down the inclined plane to Point B. The sphere is in free fall between Points B and C and first hits the floor at Point C, a horizontal distance X from the bottom of the inclined plane.
Figure 2 shows how X varies with 
for different H if the sphere rolls from Point A to Point B. Figure 3 shows h.ow X varies with for different H if the sphere slides from Point A to Point B.
13. For the sliding sphere at = 10°, if H = 0.5 m, X would most likely be:
Your Answer is
Correct Answer is A
Explanation
Put value questions. Looking at figure 3, as H gradually decreases, the corresponding ordinate is also smaller. When the abscissa θ=10°, the ordinate X corresponding to H=0.5 m should be smaller than the ordinate X of H=1.0 m, that is, less than 0.56 m
