The relative angular speed of hour hand and minute hand of a clock is (in rad/s)

Options

  1. A9 1860
  2. B11 21600
  3. C4 243
  4. D7 1480

Correct answer

B. 11 21600

Step-by-step solution

We know angular speed of the hour and minute hand of the clock are given by, _h= 2 12 3600 and _m= 2 3600 respectively. Therefore, the relative angular velocity is just the difference between these values: = 2 3600 - 2 12 3600 = 2 3600 ( 11 12 )= 11 21600 radians per second
