During a circus act, one performer swings upside down hanging from a trapeze holding another, also upside-down, performer by the legs. if the upward force on the lower performer is three times her weight, how much do the bones (the femurs) in her upper legs stretch? you may assume each is equivalent to a uniform rod 35.0 cm long and 1.80 cm in radius. her mass is 60.0 kg.

Intro: a solid ball of radius rb has a uniform charge density ρ. part a: what is the magnitude of the electric field e(r) at a distance r> rb from the center of the ball? express your answer in terms of ρ, rb, r, and ϵ0. part b: what is the magnitude of the electric field e(r) at a distance r express your answer in terms of ρ, rb, r, and ϵ0. part c: let e(r) represent the electric field due to the charged ball throughout all of space. which of the following statements about the electric field are true? check all that apply. e(0) = 0 e(rb)=0 limr→∞e(r)=0 the maximum electric field occurs when r=0 the maximum electric field occurs when r=rb the maximum electric field occurs as r→∞.
