Question

weight of solid in air is 70gf and in water is
55gf. What is the upthrust of water? What is
the volume of solid? what is Rd of solid?​

Answer 1

Answer:

Let m be the mass of the object.

Actual weight of the object, W = 50 gf = 50g

N

Apparent weight of the object, Wa = 44 gf=

44g N

Let the buoyancy be B.

Now,

Wa = W- B

=B = 50g - 44g

=>B = 6gN=> Vd = 50

The buoyancy is given by,

B V(density of water)g

=>B V(1000)g = 6g

=>V = 6/1000 = O.006 m3

This is the volume of the object.

Now, Vd = 50

->d = 50V = 50/0.006

=>d 8333.33 kg/m3

This is the density of the solid.

This is the upthrust on the object.

Let 'd' be the density of the object, and V'

be its volume.

Weight, W = Vdg = 50g
