A force \( \mathrm{F}=(10 \mathrm{t}) \mathrm{N} \) is applied on pulley \( \mathrm{P}_{1} \) as shown in the figure, where \( \mathrm{t} \) is time in second. Find the time when block math xmlns=http://www.w3.org/1998/Math/MathMLmi mathvariant=normalA/mi/math loses contact with floor. [Assume pulleys and strings to be massless]
