Question

A ball of density 7g/cm³ is immersed in water whose volume is 100 cm³ . Find the upthrust acting on it

Answer 1

Answer:7000gf

Explanation: as

Volume =100 cm³

Density =7g/cm³

Acceleration due to gravity =10m/s²

Upthrust =volume *density *gravity

= 100*7*10

=7000gf

Hope this answer helps you

Answer 2

Answer:

6830gf

Explanation:

Upthrust = V p g

V is volume of body submerged.

p is density of liquid

g is acceleration due to gravity

Volume is 100 cm^3

Density is 7g/cm^3

Acceleration due to gravity is 9.8m/s^2

100×7×9.8

70×98

6830gf
