Question

The angular velocity of a second hand of a clock is :

• A. π/3 rad/s
• B. π/30 rad/s
• C. π/5 rad/s
• D. 2π rad/s

Answer 1

The correct option is B

π/30 rad/s

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

Angular velocity of second's hand;

ω = 2π/60 = π/30 rad/s
