A truck of mass M is moved under a force F. If the truck is then loaded with an object equal to the mass of the truck and the driving force is halved, then how does the acceleration change?

From the Newton's second law, We know that,

\(F\ =\ \frac{m}{a}\)
\(F\ =\ m \times a\)

Acceleration of the truck becomes

\(2\ times\) of its initial value
\(\frac{1}{4}^{th}\) of its initial value
\(4\ times\) of its initial value
\(\frac{1}{2}^{th}\) of its initial value
