Find the apparent weight of a metallic block of density 5 ~g ~cm ⁻³ and dimensions 5 ~cm 5 ~cm 5 ~cm , in water.

Step-by-step solution

Density of metallic block, =5 ~g ~cm ⁻³ Volume of block, V=5 ~cm 5 ~cm 5 ~cm Upthrust force on the metallic block in water, array rlr F₁ & =m g & & = _w V g & [ _w=1 ~g ~cm ⁻³ ] & =V g=5 5 5 g & & =5 5 5 g f & array Apparent weight = Weight of block - Upthrust force aligned & =m g-5 5 5 g f & =(m-5 5 5) g f & =( V-5 5 5) g f & =(5 5 5 5-5 5 5) g f & =5 5 5(5-1) g f & =5 5 5 4 g f aligned
