A ball rises to surface at a constant velocity in liquid whose density is 4 times greater than that of the material of the ball. The ratio of the force of friction acting on the rising ball and its weight is

Options

  1. A3: 1
  2. B4: 1
  3. C1: 3
  4. D1: 4

Correct answer

A. 3: 1

Step-by-step solution

Frictional force = Viscous Force =V ( ₁- ₂ ) g Weight = mg = V ₁ ~g Where ₁ is the density of ball and ₂ is density of liquid. array ll & ₂=4 ₁ & V ( ₁-4 ₁ ) g=V (-3 ₁ ) g . & Frictional force =3 V ( ₁ g ) & Frictional force Weight = 3 1 =3: 1 ratio array
