the fridge from the earth?
A. 800 N, to the left
B. 600 N, to the left
C. none of the given
✓ What is the magnitude and direction of the pushing force on
the fridge from the hand?
D. 800 N, to the right
✓ What is the magnitude and direction of the normal force on
the fridge from the floor?
E. 200 N, up
F. 800 N, up
What is the magnitude and direction of the friction force on
the fridge from the floor?
G. 200 N, to the right
What is the net force on the box?
H. 200 N, to the left
1. 600 N, to the right
J. 200 N, down
K. 800 N, down
L. zero, therefore no direction
