select the correct answer.\nin which situation is the maximum possible work done?\na. when the angle between…

Explanation:

Step1: Recall work - formula

The work - done formula is $W = Fd\cos\theta$, where $W$ is work done, $F$ is the force applied, $d$ is the displacement, and $\theta$ is the angle between the force and the displacement.

Step2: Analyze the range of cosine function

The cosine function $\cos\theta$ has a range of $[- 1,1]$. The value of $\cos\theta$ is maximum when $\theta = 0^{\circ}$, and $\cos(0^{\circ})=1$.

Step3: Determine the situation for maximum work

Since $W = Fd\cos\theta$, and $F$ and $d$ are non - negative, when $\cos\theta$ is maximum ($\cos\theta = 1$ at $\theta = 0^{\circ}$), the work done $W$ is maximum.

Answer:

A. when the angle between the force and displacement is $0^{\circ}$
