$1\mathrm{.}0$ pu of active power and $0\mathrm{.}3$ pu of reactive power. Given that its synchronous reactance is $0\mathrm{.}6$ pu$,$ calculate the magnitude and phase of its internal emf. Use the terminal voltage as the reference for the angles.

P$4\mathrm{.}16$ A generator synchronized to the grid operates at its nominal voltage and supplies $1\mathrm{.}0$ pu of active power and $-0\mathrm{.}15$ pu of reactive power. Given that its synchronous reactance is $0\mathrm{.}6$ pu$,$ calculate the magnitude and phase of its internal emf. Use the terminal voltage as the reference for the angles.
