Answer:
0.25 N
Explanation:
The density of the ball () = 0.0839 g/cm³ = 83.9 kg/m³
The density of water () = 1000 kg/m³
diameter = 3.77 cm = 0.0377 m
radius of ball = 0.0377/2 = 0.01885 m
The volume (V) =
Let us assume the acceleration due to gravity (g) = 9.8 m/s²
Hence:
The force is required to hold it completely submerged under water (F) is:
F = 0.25 N
