When one electron is taken towards the other electron, then the electric potential energy of the system
1 Becomes zero
2 Remains unchanged
3 Increases
4 Decreases
Explanation:
Potential energy of two electron system is \( = \frac{{\left( { - e} \right)\left( { - e} \right)}}{{4\pi {\varepsilon _0}r}} = \frac{{{e^2}}}{{4\pi {\varepsilon _0}r}}\) As \(r\) decreases, potential energy increases.

A system of two charges separated by a certain distance apart stores electrical potential energy. If the distance between them is increased, the potential energy of the system,
1 May increase or decrease
2 Increases in any case
3 Remains the same
4 Decreases in any case.
Explanation:
Case 1: For unlike charges When one of the charges is negative, \({q_1}{q_2} < 0,\) therefore the potential energy of the system is negative. Now, if distance between the charges is increased, potential energy of the system will increase. Case II : For like charges (both positive or both negative) \({q_1}{q_2} > 0,\) therefore potential energy of the system is positive. Now, if distance between the charges is increased potential energy of the system will decrease.

If electric potential energy of given system is positive, then
1 \({2 Q>3 q}\)
2 \({2 Q < 3 q}\)
3 \({Q>2 q}\)
4 \({Q>3 q}\)
Explanation:
\({\dfrac{2 k Q^{2}}{a}-\dfrac{k Q q}{a}-\dfrac{2 k Q q}{a}>0}\) \({\Rightarrow \dfrac{2 k Q^{2}}{a}>\dfrac{3 k Q q}{a}}\) \({\Rightarrow 2 Q>3 q}\)
