In this experiment, if, say 20 kg are placed on the left side, can the plank be balanced with only 10 kg on the right side?   Group of answer choices 1-Yes, if the 10 kg are as far from the fulcrum as the 20 kg. 2-Yes, if the 10 kg are placed half as far from the fulcrum as the 20 kg. 3-No, because then the sum of torques will not be zero 4-Yes, if the 10 kg are placed twice as far from the fulcrum as the 20 kg. 5-No, because then the sum of forces will not be zero
