a
tan−1ag
b
tan−1ga
c
sin−1ag
d
cos−1ga
detailed solution
Correct option is A
When the train is at rest or moving with a uniform velocity, the plumb line hangs vertically along OB . If the train moves with an acceleration a, the plumb line gets inclined along OC, the direction of the resultant of accelerations a and g.
