A horizontal platform moves up and down simple harmonically, the total vertical movement being \( 10 \mathrm{~cm} \). What is the shortest period permissible, if objects resting on the platform are to remain in contact with it throughout the motion ? (Take \( g=980 \mathrm{~cm} \mathrm{~s}^{-2} \) ).https://bit.ly/YTAI_PWAP https://www.pw.live
