A mass $m$ is located in space within a uniform gravitational field. As the mass undergoes a displacement $x$ from P to Q, it loses potential energy $E$. Which row correctly states both the magnitude and the direction of the acceleration due to gravity in this field?
- Amagnitude $=\frac{E}{mx}$, direction $\rightarrow$
- Bmagnitude $=\frac{E}{mx}$, direction $\leftarrow$
- Cmagnitude $=\frac{E}{x}$, direction $\rightarrow$
- Dmagnitude $=\frac{E}{x}$, direction $\leftarrow$
