minus-squareLimitless_screaming@kbin.sociallinkfedilinkarrow-up4·1 year agoIn this case yes, but if q1 was -20μC, q2 was 30μC, and r was 0.5m, then using -20μC as it is would make F equal to -21.6N which is just 21.6N of attraction force between the two charges.

minus-squareLimitless_screaming@kbin.sociallinkfedilinkarrow-up1·1 year agoI am not saying that’s wrong, just that there’s 21.6N of attraction force between the two charges not -21.6N.
minus-squareBene7rddso@feddit.delinkfedilinkarrow-up3·1 year agoNo, if the force is negative it acts in the opposite direction
minus-squarePelicanen@sopuli.xyzlinkfedilinkarrow-up5·1 year agoYes, and a force acting in the opposite direction of the distance is an attractive force.

But those are the same thing.
