A mass $m$ is placed in a uniform gravitational field. As the mass undergoes a displacement $x$ from P to Q, it loses potential energy $E$. Which row correctly gives 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: $\leftarrow$
