Question

A body when fully immersed in a liquid of specific gravity 1.2 weighs 44 gwt. The same body when fully immersed in water weighs 50 gwt. The mass of the body is (A) 36 g (B) 48 g (C) 64 g (D) 80 g

Tardigrade Admin · Accepted Answer

Balancing equation W=m g-V ρ g Hence, 44=m-1.2 V ...(i) 50=m-V ...(ii) On solving Eqs. (i) and (ii) we get m=80 g

Q. A body when fully immersed in a liquid of specific gravity $1.2$ weighs $44 g wt$ . The same body when fully immersed in water weighs $50 g wt$ . The mass of the body is

36 g

48 g

64 g

80 g

Balancing equation
$W = m g - V ρ g$
Hence,
$44 = m - 1.2 V$ ...(i)
$50 = m - V$ ...(ii)
On solving Eqs. (i) and (ii) we get
$m = 80 g$
