The first of two identical boxes of mass m is sitting on level ground. The second box is sitting on a ramp that makes a 20° angle with the ground. The normal force of the level ground on the first box is NL; the normal force of the ramp on the second box is NR. Which statement is correct?

◦
NR = NL = mg.

◦
NL = mg; NR = mg sin 20°.

◦
NL = mg; NR = mg cos 20°.

◦
NL = mg; NR = −mg cos 20°.

◦
NR = −NL = −mg.
