What will be the minimum speed of the roller-coaster so that the passenger at the top, when becomes upside down, does not fall out? Consider the acceleration due to gravity as and the radius of curvature of the roller coaster is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
Now balancing the force at the top the centripetal force should be the same as the wight of the body, it means, mv2R=mg⇒v=gR, the values are given in the above question, R=10 m, it means, v=10×10=10 m s-1.
