Solution

Potential energy of the dipole in the unifrom electric field is given by:
$U = - P . E U = - P E \cos θ f o r m a x i m u m e n e r g y, θ = 0^{o} U_{m a x} = - P E f o r h a l f o f t h e v a l u e U = - \frac{P E}{2} \cos θ = \frac{1}{2} θ = 60^{o}$

where $θ$ is the angle between P and E.
