What is the ratio of the angular speeds of the minute hand second hand of a clock ?

Options

A. `1 : 12`
B. `12 : 1`
C. `1 : 60`
D. ` 60 : 1`

Answer

D

Explanation

Angular speed of minute hand `omega_(m) = (1)/(60)`
Angular speed of second hand `omega_(s) = (1)/(3600)`
` omega_(m) : omega_(s) = (1)/(60): (1)/(3600)`
`= (1)/(1) : (1)/(60)`
= 60 :1
