how is electrostatic force related to the magnitude of charge on the two objects? keeping the same separation distance for all trials systematically after the charges of the objects and record the force. hey symptomatic and purposeful changes such as doubling tripling and quadrupling of charge

The answer is 4f======since electrostatic force is given by    we let f be the electrostatic force when  r = 1 m    if we let  denote the electrostatic force when the distance is decreased so that r = 0.5m, then    we established earlier that f = kq₁q₂. therefore    the force will now be 4f.
