Vedclass · Answer

(D) The volume of the block $V = 5 \, cm 	imes 5 \, cm 	imes 5 \, cm = 125 \, cm^3$.The density of the block $ho = 5 \, g \, cm^{-3}$.The density of water $\sigma = 1 \, g \, cm^{-3}$.The apparent weight $W_{app}$ is given by the formula $W_{app} = V(ho - \sigma)g$.Substituting the values,$W_{app} = 125 	imes (5 - 1) 	imes g$ (in units of force).Since $1 \, g$ mass corresponds to $1 \, gf$ weight,the apparent weight in $gf$ is $V(ho - \sigma) = 125 	imes 4 = 500 \, gf$.Comparing this with the given options,$500 = 4 	imes 5 	imes 5 	imes 5 \, gf$.
