Question

(B) The electrical potential energy $(U)$ of a system of two point charges $Q_1$ and $Q_2$ separated by a distance $r$ is given by $U = \frac{1}{4\pi\

Vedclass · Accepted Answer

The electrical potential energy of a proton-electron system will increase if the separation between the two is decreased.

Vedclass · Answer

(B) The electrical potential energy $(U)$ of a system of two point charges $Q_1$ and $Q_2$ separated by a distance $r$ is given by $U = \frac{1}{4\pi\varepsilon_0} \frac{Q_1 Q_2}{r}$.$1$. For like charges (e.g.,two protons or two electrons),$Q_1 Q_2 > 0$. As the separation $r$ decreases,the denominator decreases,causing the potential energy $U$ to increase.$2$. For unlike charges (e.g.,a proton and an electron),$Q_1 Q_2 $3$. Conversely,for unlike charges,if the separation $r$ increases,the potential energy $U$ increases (becomes less negative).Evaluating the options:- Option $A$: Like charges,$r$ decreases $\rightarrow$ $U$ increases. (Correct statement)- Option $B$: Unlike charges,$r$ decreases $\rightarrow$ $U$ decreases. (Incorrect statement)- Option $C$: Unlike charges,$r$ increases $\rightarrow$ $U$ increases. (Correct statement)- Option $D$: Like charges,$r$ decreases $\rightarrow$ $U$ increases. (Correct statement)Therefore,the $WRONG$ statement is $B$.
