What is the lower limit of the electric force between two particles placed at a certain distance?

A

`1/(4piepsilon_0) (2e^2)/r`

B

`1/(4piepsilon_0) e^2/r^2`

C

`1/(2piepsilon_0) e/r^2`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
`F=1/(4piepsilon_0).(q_1q_2)/r^2`
`(q_1)_(min)(q_2)_(min)=e_2`
`:. F_(min)=1/(4piepsilon_0) e^2/r^2`
