An electromagnetic wave with an amplitude of 8.00 V/m boils a cup of water in 4.00 minutes. (The units for the amplitude are here because we always need units, but they are not relevant to answering the question). If the amplitude was increased to 16.0 V/m, but everything else (e.g., frequency, distance of cup from source etc.) stayed the same, how long would it take to boil the same cup of water? Enter your answer in minutes.
