Abox is being pulled by two ropes. eduardo pulls to the left with a force of 500 n, and clara pulls to the right with a force of 200 n. the box moves because of the two forces applied to it. leon records the forces and direction of the forces acting on the box in his lab notebook. in the table, which force has the wrong direction?

tension by eduardo
tension by clara
kinetic friction
gravity

Draw a diagram to illustrate the problem, as shown below.

m = mass of the box, kg
mg =  weight of the box, N, acting downward

Because of Newton's 3rd law, a normal force of N = mg acts upward on the box.
C = 200 N, the force applied by Clara, horizontally to the right
E = 500 N, the force applied by Eduardo, horizontally to the left.

Because E is greater than C, the box will move left.
The frictional force, F, will resist the initial motion. Its magnitude is
F = μN = μmg, where μ = kinetic coefficient of friction.
F acts horizontally to the right.

From the given table, we can conclude that
Normal force acting upward is correct
Tension by Eduardoacting left is correct.
Tension by Clara acting right is correct.
Kinetic friction acting left is Incorrect.
 Gravity acting downward is correct.correct

The direction of the kinetic friction force is incorrect
