what is the relationship between size and acceleration when two forces are applying force on each other?
a the smaller object has a less noticeable acceleration in comparison with the bigger object.
b the smaller object has a more noticeable acceleration in comparison with the bigger object.
c the smaller object always has acceleration and the bigger object never does.
d the smaller object never has acceleration and the bigger object always does.

Explanation:

Step1: Recall Newton's second law

$F = ma$ (where $F$ is force, $m$ is mass, $a$ is acceleration).

Step2: Analyze for two objects with same force

If $F_1=F_2$, then $a=\frac{F}{m}$. Smaller $m$ (smaller object) gives larger $a$.

Answer:

B. The smaller object has a more noticeable acceleration in comparison with the bigger object.
