1.	How how much work is done in raising a stone of mass 5 kg to a height of 5 metre.its answer is 245 Joule.tell me solution
Answer» $\star$ LOSS of weight in WATER = weight in air / specific GRAVITY = 5/3 Weight of STONE in water = 5-5/3 = 10/3 Force = 10/3 x 9.8 = 98/3 Work done = 4 x 98/3 = 130.666 $\implies$ 130.7(appx)J *Mark* me as *brainliest* *please*

Answer»

$\star$ LOSS of weight in WATER = weight in air / specific GRAVITY = 5/3

Weight of STONE in water = 5-5/3

= 10/3

Force = 10/3 x 9.8

= 98/3

Work done = 4 x 98/3

= 130.666

$\implies$ 130.7(appx)J
