juan da una vuelta completa en visicleta a una pista circular de 10m de radio¿cuanto vale el desplasamiento?

Definitely the indoraptor

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.

The answer is: 6.3mi got it right
