A particle is executing SHM with a period of T sec and amplitude of a metre.

The shortest time it takes to reach a point A/√2 m from its mean position in sec will be ?

t/8 is the time taken becoz if we represent the question in a radiant it will form 45 degees with the horizontal so if we take the total time for full oscillation as 360 degrees and  for travelling 45 degrees it will take t/8
