MHT CET Physics question
A coin is placed on a horizontal platform which undergoes vertical simple harmonic motion of angular frequency . The amplitude of oscillation is gradually increased. The coin will leave contact with the platform for the first time [AIEEE 2006, AIIMS 2008]
Answer: (A)
Solution
Contact is lost when the downward acceleration of the platform exceeds , i.e. when ; this first happens at the highest point once .
