Please help with the last two questions. Thanks you.

A robot pushes a 20-kg box on the horizontal surface as part of the moving job, the force is 35 N to the left shown. The box does not move. The coefficients of friction between the floor and box are µs = 0.75 and µk = 0.40. Use g = 10 m/s². Match the anwers with questions. (Hint: Draw a proper free-body diagram.) B. What is the magnitude and direction of the weight force on the box from the earth? E. What is the magnitude and direction of the pushing force on the box from the hand? H. What is the magnitude and direction of the normal force on the box from the floor? What is the magnitude and direction of the friction force on the box from the floor? What is the net force on the box? A. 200 N, to the left B. 200 N, down C. zero, therefore no direction D. 35 N, down E. 35 N, to the left F. none of the given G. 35 N, to the right H. 200 N, up 1. 35 N, up J. 200 N, to the right
