A metal sphere immersed in water weighs w₁ at 0^ C and w₂ at 50^ C . The coefficient of cubical expansion of the metal is less than that of water. Then

Options

  1. AW₁>W₂
  2. BW₁ < W₂
  3. CW₁=W₂
  4. DW₁=2 W₂

Correct answer

B. W₁ < W₂

Step-by-step solution

Apparent weight of object in water, aligned & w density of object (sphere) density of water & w d_s d_w aligned As, cubical expansion (Y) of metal is less than water, thats why ratio of density of sphere and water will greater at 50^ C than 0^ C . aligned & ( d_s d_w )_ 50^ C > ( d_s d_w )_ 0 ^ C & w₂>w₁ aligned
