Please answer this.Which graph shows correct variation of force when the distance between two charges varies?

Dear student, As per Coulomb's law electrostatic force is inversely proportional to the square of distance between charges. Therefore , force will decrease when we increase the value of r and since F is varying w.r.t. 1/r², so the graph of F-r will be decreasing and curve ( non linear). Therefore D is correct option as value of F decreasing with increasing r in curve manner. Regards
