alleryStart learning →A force doubles and its perpendicular arm becomes one-third. New moment?
ASix times the old
BThree-halves of the old
CTwo-thirds of the old
DOne-sixth of the old
Answer & Solution
Correct answer: C. Two-thirds of the old
Moment scales with both factors, so doubling force and dividing its arm by three multiplies moment by two-thirds.
