Because of the conditions that give rise to them, tornadoes do not have
the widespread destructive effects of hurricanes. Nevertheless, the
winds encountered in some tornadoes are even greater than those at
the eyewall of a hurricane. Suppose a small pebble is swept up in a tor-
nado. The pebble is 3.81 m from the center of the tornado and has a
tangential speed equal to that of the surrounding wind: 124 m/s. What
is the magnitude of the centripetal acceleration of the pebble?

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→∞.
