A metallic block of density 5 gm c m − 3 and having dimensions 5 cm × 5 cm × 5 cm is weighed in water. Its apparent weight will be Options: A . &nbsp 5 × 5 × 5 × 5 g f B . &nbsp 4 × 4 × 4 × 4 g f C . &nbsp 5 × 4 × 4 × 4 g f D . &nbsp 4 × 5 × 5 × 5 g f

Answer: Option D : D Apparent weight = V ( ρ − σ ) g = l × b × h × ( 5 − 1 ) × g = ( 5 × 5 × 5 × 4 × g ) dyne = ( 4 × 5 × 5 × 5 ) g f

Question -

A metallic block of density 5 gm $c m^{- 3}$ and having dimensions 5 cm $\times$ 5 cm $\times$ 5 cm is weighed in water. Its apparent weight will be

Options:

A .

5 \times 5 \times 5 \times 5 g f

B .

4 \times 4 \times 4 \times 4 g f

C .

5 \times 4 \times 4 \times 4 g f

D .

4 \times 5 \times 5 \times 5 g f

Answer: Option D
:
D

Apparent weight

$= V (ρ - σ) g = l \times b \times h \times (5 - 1) \times g$

$= (5 \times 5 \times 5 \times 4 \times g)$ dyne = $(4 \times 5 \times 5 \times 5) g f$
