Which relation correctly gives the arc-length displacement

s

of the bob of a simple pendulum in terms of the string length

L

and the angular displacement

\theta

(with

\theta

expressed in radians)? (a)

s = 2L\sin\dfrac{\theta}{2}

(b)

s = L\theta

(c)

s = L\sin\theta

(d)

s = L\theta^{2}
