A clock has a continuously moving second's hand of $0.1 m$ length. The average acceleration of the tip of the hand (in units of ${ms}^{- 2}$ ]) is of the order of :

Options:

Answer:

Solution:

The instantaneous acceleration of tip is given by

$ac = ω^{2} R = {(\frac{2 π}{60})}^{2} \times 0.1 = \frac{1}{900} \approx 10^{- 3}$
