# Terrorist attack

Logic Level 3

A group of terrorists has attacked a country. A shop was delivering $$3^{15}-2$$ balls. The terrorists placed a bomb, perfectly identical to the balls. The government found that there was a bomb and also that the bomb is heavier than rest of the balls. They brought an accurate weighing machine on which load is placed on both sides. They knew they had less time. So how many minimum number of trials are required to identify the bomb and start the process of bomb defusing?
