A) \[{{\tan }^{-1}}(a/g)\]
B) \[{{\tan }^{-1}}(g/a)\]
C) \[{{\cos }^{-1}}(a/g)\]
D) \[{{\cos }^{-1}}(g/a)\]
Correct Answer: A
Solution :
When car moves towards right with acceleration a then due to pseudo force the plumb line will tilt in backward direction making an angle \[\theta \] with vertical. From the figure, \[\tan \theta =a/g\] \[\therefore \] \[\theta ={{\tan }^{-1}}(a/g)\]You need to login to perform this action.
