A mass $m$ is placed in space within a uniform gravitational field. As the mass travels a displacement $x$, from P to Q, it loses potential energy equal to $E$. Which row gives the correct value for 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 $\leftarrow$
