Explanation 1) Concept: There are three forces acting on the bubble – buoyant force ( F b ) , weight, and normal reaction. As the ball is stationary, net force acting on the ball is zero. Using this concept, we can find ( M b ) . 2) Formula: i) F n e t = 0 ii) F b = M b g = ρ b V b g iii) W = M b g iv) V = 4 3 π r 3 3) Given: i) Radius of the ball r = 2 × 10 - 2 m ii) N = 9.48 × 10 - 2 N iii) Density of milk ( ρ _ m ) = 1.03 g / c m 3 = 1030 k g / m 3 4) Calculations: Volume of the milk displaced by the ball (Vmilk) = Volume of the ball (Vb) V m i l k = 4 3 π r 3 V m i l k = 4 3 × 3
