A mass $m$ is located 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 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 $\leftarrow$
