Which produces the largest torque?

Question

30.0 N perpendicular to the center of rotation at a radius of 1.5 m

30.0 N perpendicular to the center of rotation at a radius of 0.25 m

60.0 N perpendicular to the center of rotation at a radius of 1.0 m

60.0 N perpendicular to the center of rotation at a radius of 0.5 m

Answer 1

Moment=force*length*sinAngle

example: 30*.25=7.5N-m

do the other three, which is largest? I bet it has a 60 in it.
