Answer 1

answer) according to the newtons law of motion we have the general rule that  the sum of the forces are zero if the forces are equal and opposite

the normal force of the sled and girl is equal to the weight and they act in opposite direction so they cancel each other out

now in horizontal direction the tension produced by the pull is greater because if friction was greater than the sled would not speed up

so the correct option is =zero,pointing to the right.
