A plumb line is suspended form a ceiling of a car moving with horizontal acceleration of ɑ. What will be the angle of inclination with vertical?
Options
(a) tan¯¹ (ɑ/g)
(b) tan¯¹(g/ɑ)
(c) cos¯¹(ɑ/g)
(d) cos¯¹(g/ɑ)
Correct Answer:
tan¯¹ (ɑ/g)
Explanation:
When car moves towards right with acceleration a then due to pseudo force the plumb line will tilt in backward direction making an angle θ with vertical.
