Question

A block of steel of size 5 cm × 5 cm × 5 cm is weighed in water. If the relative density of steel is 7, its apparent weight is

• A. 6 × 5 × 5 × 5 gf
• B. 4 × 4 × 4 × 7 gf
• C. 5 × 5 × 5 × 7 gf
• D. 4 × 4 × 4 × 6 gf

Answer 1

Answer: (A)

6 × 5 × 5 × 5 gf

Answer 2

Apparent weight = $V ( \rho - \sigma ) g$

= $5 \times 5 \times 5 ( 7 - 1 ) g$= $6 \times 5 \times 5 \times 5 g f$
