Chante rides her motorcycle around a curve in the road. The section of the curve can be approximated by a circle of radius 305 m. If she has a centripetal acceleration of 1.66 m/s^2, what is Chante's tangential speed?

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.
