## The correct option is D 10,20,40Step 1: Conclusion from triangle law of additionFrom the triangle law of vector addition,The resultant must be zero if the sum of two forces ≥ remaining forceStep 2: Analysing optionsIn all the options except D, the sum of two forces is greater or equal to the remaining forceHowever, For option D, 10+20=3030<40Hence, the resultant can not be zero for option D.∴ Option D is the correct answer.
