NEET Physics Question (2024) — Solution

Question

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 x_1, x_2 and x_3 are their respective angular distances in 1 minute then the factor which remains constant (k) is

Options

  1. A. _1 x_1 = _2 x_2 = _3 x_3 =k
  2. B. _1 x_1= _2 x_2= _3 x_3=k
  3. C. _1 x_1^2= _2 x_2^2= _3 x_3^2=k
  4. D. _1^2 x_1= _2^2 x_2= _3^2 x_3=k

Answer

A. _1 x_1 = _2 x_2 = _3 x_3 =k

Step-by-step solution

_1= 2 60 ; x_1= 2 60 60=2 _2= 2 3600 ; x_2= 2 3600 60= 2 60 _3= 2 3600 12 ; x_3= 2 3600 12 60= 2 720 _1 x_1 = _2 x_2 = _3 x_3 = 1 60 =k
