A) \[14\,\,m\]
B) \[28\,\,m\]
C) \[35\,\,m\]
D) \[7\,\,m\]
Correct Answer: C
Solution :
Key Idea: The sphere will fly off when the normal reaction at the surface of sphere is zero. Let \[P\] be the instantaneous position of the particle during its sliding from the top\[A\]. \[N\]be the normal reaction at the surface of sphere, thus supplies the necessary centripetal force thus.You need to login to perform this action.
