Spheres of iron and lead having same mass are completely immersed in water. Density of lead is more than that of iron. Apparent loss of weight is w₁ for iron sphere and w₂ for lead sphere, Then, w₁ w₂ is

Options

  1. A>1
  2. B=1
  3. Cbecome 0 and 1
  4. D=0

Correct answer

C. become 0 and 1

Step-by-step solution

We have, Relative density = Actual weight Loss of weight (R D)_ iron = w w₁ or w₁= w (R D)_ iron (R D)_ lead = w w₂ or w₂= w (R D)_ lead w₁ w₂ = (R D)_ iron (R D)_ lead >1
