If an objects mass doubles while the net force on it remains constant thena) the acceleration is reduced by 4 timesb) the acceleration is increased by 2 timesc) the acceleration is reduced by 2 times d) the acceleration is increased by 4 times

ANSWER:
c) the acceleration is reduced by 2 times
STEP-BY-STEP EXPLANATION:
We have that the force formula is the following:
[tex]\begin{gathered} F=m\cdot a \\ \text{ solving for a} \\ a=\frac{F}{m} \end{gathered}[/tex]Now if the mass doubles, then:
[tex]\begin{gathered} a=\frac{F}{2m} \\ a=\frac{1}{2}\cdot\frac{F}{m} \\ a=\frac{1}{2}a \end{gathered}[/tex]Which means that the acceleration would be halved
