Question

a body of mass 3.5 kg displaces 1000cm of water when completely immersed in it .calculate i)the volume ii)the upthrust of the body iii)the apparent weight of the body ​

Answer 1

Answer:

1.Volume of body is equal to the volume of water displaced.

Vb=V w

=1000 cm

=0.001 m

(ii) Upthrust B=V b ρ w

g=0.001×1000×10=10 N

(iii) True weight W=3.5×10=35 N Apparent weight W a

=W−B=35−10=25 N or 2.5 kg
