The Attempt at a Solution
Applying conservation of potential energy,## mgL (1 - \cos{ \theta_0}) = mg(L + \delta ) (1 - \cos{ \theta_1}) ##
## \cos{ \theta_1} - \cos{ \theta_0} = \frac { \delta - \delta \cos{ \theta_1}} L ##Taking the approximation,
## ( \theta_0 - \theta_1)(\theta_0+ \theta_1) =\frac { 2 \delta } L ##
## \theta_0 -\theta_1 = \frac { \delta }{ L \theta_0} ##
## \theta_1 = \theta_0 \left (1 - \frac { \delta }{ L {\theta_0}^2} \right ) ##
Is this correct?
