Question

Volume 100 cm3 is completely immersed in water determine the upthrusr of the body density of water is equal to 10

Answer 1

Answer:

density of water=10gcm^-3(assuming the unit,as it was not mentioned by you,and even in c.g.s units,density of water is not 10)

Volume of water displaced by body=volume of body=100cm^3

therefore,

Density=Mass/Volume

or,10=Mass/100

or,Mass=10×100=1000g=1kg

Thus,upthrust on body=weight of displaced water=Mass×Acceleration due to gravity=1×9.8=9.8
