Porfa me pueden ayudar
¿en que se diferencia el planteamiento hecho por aristoteles y galileo con respecto al movimiento de un cuerpo en un plano horizontal?

Ibelieve the correct answer would be c.

//(b) both involve the use of levers;

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.
