I think there is a small twist in the question. Normally if
it was a closed room and the plates are stationary then
according to the principle of natural convection the
vertical plate will emit more heat and will cool faster than
the horizontal one. But here its mentioned that the room is
open, so there may be some air flow horizontally too. So the
answer depends on the rate of air flow too. But nothing is
mentioned here. So we cant assume huge air flow. Note that
the natural convection effect is also there. So the more
correct answer would be the vertical plate....
