The potential energy and electric field?

ELECTRIC POTENTIAL, POTENTIAL ENERGY & WORK DONE BY THE ELECTRIC FIELD. Help..?

  • Answer:

    find the horizontal electrical force: use tan20° = Fe/Fg with Fg = gravitational force Fe = Fg*tan20 = 0.005*9.81*tan20 = 0.017853 N find the field strength E electrical force = E*Q E = Fe/Q E = 0.017853/(20*10^-6) E = 892.65 V/m V = E*d = 892.65*0.08 = 71.41 Volt <--- ans. OG
