If you want the same acceleration with masses M and 4M, the force applied on the mass M is
A) the same as for the mass 4M.
B) four times the force applied on the mass 4M.
C) one-fourth the force applied on the mass 4M.
D) twice the force applied on the mass 4M.
E) one-half the force applied on the mass 4M.

Question

Quizplus · Accepted Answer

The force applied is proportional to the mass, so if the acceleration is the same for masses M and 4M, the force applied on M must be one-fourth of the force applied on 4M.
