snehahahal 0 Posted September 30, 2020 Report Share Posted September 30, 2020 I have been cracking my head on this one MCQ for too long now. For the following question, I am getting the answer W > P + R which is wrong: The diagram shows a girl attempting (but failing) to lift a heavy suitcase of weight W. The magnitude of the vertical upwards pull of the girl on the suitcase is P and the magnitude of the vertical reaction of the floor on the suitcase is R. Write an equation correctly relates W, P and R. The answer is W = P + R As the question said that she is failing to lift the suitcase, I thought the Weight acting downwards would be more than the sum of P and R. Why is that wrong? Also, just to confirm, R is the force acting upwards right?? Thank you so muchhhh Reply Link to post Share on other sites
