Let ₁, ₂ and ₃ be the angular speed of the second hand, minute hand and hour hand of a smoothly running analog clock, respectively. If x₁, x₂ and x₃ are their respective angular distances in 1 minute then the factor which remains constant (k) is

Options

  1. A₁ x₁ = ₂ x₂ = ₃ x₃ =k
  2. B₁ x₁= ₂ x₂= ₃ x₃=k
  3. C₁ x₁^2= ₂ x₂^2= ₃ x₃^2=k
  4. D₁^2 x₁= ₂^2 x₂= ₃^2 x₃=k

Correct answer

A. ₁ x₁ = ₂ x₂ = ₃ x₃ =k

Step-by-step solution

₁= 2 60 ; x₁= 2 60 60=2 ₂= 2 3600 ; x₂= 2 3600 60= 2 60 ₃= 2 3600 12 ; x₃= 2 3600 12 60= 2 720 ₁ x₁ = ₂ x₂ = ₃ x₃ = 1 60 =k
