Answer:

(C)

Explanation:

Second’s hand of a clock completes one turn in one second. i.e 1 revolution per minute.

Angular speed = angle swept by the radius vector ÷ time taken.

Angle swept for one complete rotation is 2π radians.

Thus, Angular velocity of second’s hand,

ω = 2π/60

   = π/30 rad/s

Result:

π/30 rad/s
