Correct Answer:- Option ®
QuestionS2:-A 10 kg chandelier light is suspended from the ceiling of a building using four equal length chains. The tap ends of the chains are secured equally spaced on the
circumference of a circular plate which is screwed on the ceiling. The circular plate has a diameter of 1.2 meters and the maximum permissible force in any chain is limited to 25 2۷
Then the minimum vertical distance between the ceiling and chandelier is (take g = 10 Vs").
