Along the z-axis, indicated by the dashed line on this diagram, the electric field is E = -Cz²2, where C is a positive constant. The minus sign implies the field points backwards. A particle of charge +9o and mass m is released from rest from z = on the z-axis. a) What is the particle's speed when it reaches z = and zo- %3D +20, 0? Answer in terms of qo, m, C, b) At z 0, what is the particle's acceleration?
