The diagram below shows a wooden block of dimensions 50cm by 40cm by 20cm held in a position by a string attached to the bottom of a swimming pool.

i) The three forces acting on the block are the tension (T) in the string, the weight (W) of the block and the upthrust (U) due to water.
Write an equation relating T, W and U when the block is at stationary.
ii) What is the weight of the block.
iii) What is the weight of the water displaced by the block.
iv) Determine the tension (T) on the string. (density of the block is 600kgm^-3; density of water is 1000kgm^-3)
