(Figure 1) shows a region of space with an electric field. Vertical lines indicate equipotential surfaces. A particle with charge q = -4.8 nC is initially at the location of the -20-V equipotential line. At time t = 0 the particle is released from rest. Ignore the force exerted by Earth on the particle.
Part A: Estimate the magnitude of force exerted by the electric field on the particle when it passes the 0-V equipotential line.
Part B: Estimate the magnitude of force exerted by the electric field on the particle when it passes the 80-V equipotential line.
Part D: Estimate the kinetic energy of the particle when it passes the 60-V equipotential line.
