ANSWER:
a. one-fifth as that of object 1.
STEP-BY-STEP EXPLANATION:
We have that the acceleration is given as follows:
[tex]\begin{gathered} F=m\cdot a \\ a=\frac{F}{m} \\ F=\text{constant } \\ \text{therefore} \\ a_1=\frac{F}{M} \\ a_2=\frac{F}{5M}_{} \\ \text{therefore} \\ a_2=\frac{1}{5}\cdot\frac{F}{M} \\ a_2=\frac{1}{5}\cdot a_1 \end{gathered}[/tex]Therefore, the answer is one-fifth as that of object 1.
