Answer 2

Answer:

Since half of the candle floats up when in initial equilibrium, density of the candle is half of density of water.

Thus it always remains half inside water and half outside. Thus after an hour, the length of candle would decrease by 2cm and half of it would remain in water and half outside. Thus the fall in the top of the candle would be 1cm.

Thus rate of fall of top of the candle is 1cm/h.
