The bob of a pendulum was released from a horizontal position. The length of the pendulum is $$10$$ m. If it dissipates $$10\%$$ of its initial energy against air resistance, the speed with which the bob arrives at the lowest point is: [Use, $$g = 10 \text{ m s}^{-2}$$]

A

$$6\sqrt{5} \text{ m s}^{-1}$$

B

$$5\sqrt{6} \text{ m s}^{-1}$$

C

$$5\sqrt{5} \text{ m s}^{-1}$$

D

$$2\sqrt{5} \text{ m s}^{-1}$$
