  A rope of negligible mass passes over a puley of a negligible mass attached to the ceiling. One end of the rope is held by stdent A of mass 70 kg who is at rest on the floor. The opposite end of the rope is held by student B of mass 60 kg who is suspended at rest above the floor
  
  calculate the magnitude of the force exerted on the floor by student A
  
  I said 700 N and aparently this is wrong and I don\'t see why

  If this question is asking for the normal force i got 100 n but i\'m not sure that is what it is asking for

  The suspended student B's weight is balanced by a rope force Mb*g = 588 N. This becomes an upward force on Student A. A is held in equilibrium by ground force Fg (up), rope force (up) and his weight Mb*g (down).
  Fg + 588 = Mb*g = 686 N
  Fg = 686 - 588 = 98 N
  
  If you are using 10 m/s^2 for g, you'd get 100 N for the answer. I used 9.8.

explanation: The document describes a physics problem involving two students, A and B, connected by a rope over a pulley. Student A is on the floor with a mass of 70 kg, and student B is suspended above the floor with a mass of 60 kg. The problem asks for the magnitude of the force exerted on the floor by student A. The user mentions their answer of 700 N, which is incorrect, and another user suggests that the normal force is 100 N. The correct solution is provided, showing that the force exerted on the floor by student A is 98 N (or 100 N if using \( g = 10 \, \text{m/s}^2 \)).
