A glass plate of length 10 cm, breadth 4 cm, and the thickness 0.4cm , weighs 20g in air. It is held vertically with long side horizontal and half the plate immersed in water. What will be its apparent weight? Surface tension of water = `70 dyn e//cm`.

A glass plate of length 10 cm., breadth 1.5 cm. and thickness 0.2 cm., weighs 8.2 gm. In air. It is held vertically with long side horizontal and half the plate immersed in water. What will be its apperent weight ? Surface tension of water = 73 dynes//cm.

A glass plate of length 10 cm , breadth 1.54 cm and thickness 0.20 cm weights 8.2 gm in air, It is held vertically with the long side horizontal and the lower half under water. Find the apperent weight of the plate. Surface tension of water = 73 "dyne" per cm, g = 980 "cm"//"sec"^(2)

A glass plate of lengthh 10 cm , breadth 1.54 cm and thickness 0.20 cm weight 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 =7.3xx10^(-2)N//m and =9.8ms^(-12)

A glass plate of length 0.1 m , breadth 15 xx 10^(3) m and thickness 2 xx 10^(-3)m weighs 8 xx 10^(-3) kg in air, it is held vertically with its longer side horizontal and its lower half immersed in water. If the surfaces tension of water is 72 xx 10^(-3) N//m , the apparent weight of the plate is 79.4 lambda xx 10^(-3) N . Then find lambda

A glass plate of length 8cm, breadth 3 cm and thickness 0.2cm weighs 15 g in air. What will the apparent weight of the plate if it is half immersed vertically in water its long side held hrizontal? Take, Surface tension of water =70 dyne/cm

A square glass plate of length 10 cm and thickness 0.4 cm, weight 40 g in air. It is held vertically such that its lower edge rests on water surface. What is the apparent weight of glass plate now? (Given surface tension of water = 0.073 N m^(-1) )

A clean glass plate of length 9.8 cm , breadth 4 cm an thicness 0.2 cm is suspended vertically with its long side horizontal and with half the side immersed. Pull due to suface tension will be (S.T.=0.07N//m )

Mass of a wooden piece of length 20 cm breadth 10 cm and thickness 0.5 cm is 50g. What is the density of wood ?

Two vertical glass plates 1 mm apart are dipped into water. How high will the water rise between the plates. If the surface tension of water is 70 dyne cm^(-1)
