1.	A false balance is such that the beam remains horizontal when pans are empty. An object weighs W_(1) when placed in one pan and W_(2) when placed in the other pan. The true weight of the object is
Answer» `(W_(1)+W_(2))/(2)` `SQRT(W_(1)W_(2))` `sqrt(W_(1)^(2)+W_(2)^(2))` `sqrt((W_(1)^(2)+W_(2)^(2))/(2))` ANSWER :B::C
