A small block of mass \( 2 \mathrm{~kg} \) is kept on a rough inclined surface of inclination \( \theta=30^{\circ} \) fixed in a lift. The lift goes up with a uniform speed of \( 1 \mathrm{~m} \mathrm{~s}^{-1} \) and the block does not slide relative to the inclined surface. The work done by the force of friction on the block in a time interval of \( 2 \mathrm{~s} \) ishttps://bit.ly/YTAI_PWAP https://www.pw.live
