A glass plate of length 10 cm, breadth 1.54 cm and thickness 0.20 cm weigh 8.2 g in air. It is held vertically with the long side horizontal and the lower half under water. Find the apparent weight of the plate. Surface tension of water = 7.3 × 10^−2 N/m and =9.8 m/s^2. The apparent weight of the plate is
