Question

А
A sphere of volume 20cm3 and
density 0.3cm-3 is placed on
water & Find the upthrust on
the sphere​

Answer 1

Answer:

ANSWER

Given:

Density of water =1 gcm

−3

Density of sphere =A=0.3 gcm

−3

Density of sphere =B=8.9 gcm

−3

Volume of sphere A & B=100 cm

3

To find upthrust on each sphere

Upthrust on sphere A= volume of sphere A× density of water ×g

100×1×g=100gf

Upthrust on sphere B= volume of sphere B× density of water ×g

=100×1×g=100gf

Upthrust acting on both the spheres is the same as the volume of sphere A and B inside water is the same.
