When the distance between two charged particles is halved, the force between them will become

Options

A. remains same
B. increases four times
C. reduce four times
D. None of the above

Answer

A

Explanation

As per coluolmb.s Law `F=k (q_(1)q_(2))/(r^(2))`
According to question
`F.=k((q_(1)//2)(q_(2)//2))/((r//2)^(2))=k (q_(1)q_(2))/(r^(2))=F`
Thus, force them wil remain same,.
