A 100-N little physics tyke hangs on the ends of a rope suspended over a pulley as shown. The tension in the rope is

1) 0 N. 2) 50 N. 3) 100 N. 4) 200 N. It is interesting to note that 5) the tension in the rope at its midpoint (uppermost part) is 100 N. 6) this is a modified tug-o'-war example (simply draped over a pulley). 7) the net force acting on the rope is in this case identical to the child's weight.
