The peak value of an alternating emf \( \mathrm{E} \) given by
P \( \mathrm{E}=\mathrm{E}_{0} \cos \omega t \) is \( 10 \mathrm{~V} \) and frequency is \( 50 \mathrm{~Hz} \). At

W time \( t=(1 / 600) \mathrm{s} \), the instantaneous value of emf is
(1) \( 10 \mathrm{~V} \)
(2) \( 5 \sqrt{3} \mathrm{~V} \)
(3) \( 5 \mathrm{~V} \)
(4) \( 1 \mathrm{~V} \)
