A mass m is situated in a uniform gravitational field.
When the mass moves through a displacement x, from P to Q, it loses an amount of potential energy E.
Which row correctly specifies the magnitude and the direction of the acceleration due to gravity in this field?
magnitude: $\frac{E}{{mx}}$ / direction: $ \to $
2 )
magnitude: $\frac{E}{{mx}}$ / direction: $ \leftarrow $
3 )
magnitude: $\frac{E}{x}$ / direction: $ \to $
4 )
magnitude: $\frac{E}{x}$ / direction: $ \leftarrow $
