Question

In bringing an electron towards another electron, electrostatic potential energy of the system
1. decreases
2. increases
3. becomes zero
4. remains same

Answer 1

Increases. because if we bring two electrons together, they will repel due to same -ve charge.
since U=K Q1.Q2/r^2,
U is inversely proportional to  r. therefore,as r will decrease, electrostatic potential energy will increase.

Answer 2

Heya......
