An AC generator supplies an rms emf of

110\,\text{V}

when its rotor speed is

1800\,\text{rev}\,\text{min}^{-1}

. Keeping all other factors unchanged, determine the rms emf when the rotor speed is increased to

3000\,\text{rev}\,\text{min}^{-1}

. (a)

259\,\text{V}

(b)

165\,\text{V}

(c)

183\,\text{V}

(d)

74\,\text{V}
