Time period of a simple pendulum is T. The time taken to complete 58 oscillations starting from mean position is αβT . The value of α is ___________

58 of oscillation means , distance covered=58(4A) = 5A2Thus, its coordinate is x=-A2 going towards left extreme.x=Asin⁡ωt⇒−A2=Asin⁡ωt⇒ωt=7π6⇒2πT=7π6⇒T=7T12∴α=7
