A)the same as for the mass 4M.
B)four times the acceleration of the mass 4M.
C)one-fourth the acceleration of the mass 4M.
D)twice the acceleration of the mass 4M.
E)one-half the acceleration of the mass 4M.

According to Newton's second law of motion, acceleration is directly proportional to force and inversely proportional to mass (a = F/m). Therefore, if the same force is applied to an object with mass M and another with mass 4M, the object with mass M will experience four times the acceleration of the object with mass 4M, because the acceleration is inversely proportional to the mass.
