Plot a graph showing the variation of coulomb'* forces (F) showing 1/r2, where r is the distance between two charges of each pair of charges(1uC,2uC)& (1uC,-3uC). Interpret the graph so obtained.
Force between charged particles is given by,
The graph between F and 1/r2 is a straight line of slope passing through the origin.
Magnitude of slope is more for attraction, therefore attractive force is greater than the repulsive force.
