Two equal charges of magnitude q

are at a distance of r
units apart. In which scenario will the electrostatic force between them remain the same?(1 point)

when q
is doubled and r
is quadrupled
when q is doubled and r is quadrupled

The scenario where the electrostatic force between the charges remains the same is when q is halved and r is doubled.
