Consider two points in an electric field. The potential at point 1, V1, is 32 V. The potential at point 2, V2, is 179 V. An electron at rest at point 1 is accelerated by the electric field to point 2.
Part (a) Write an equation for the change of electric potential energy ΔU of the electron in terms of the symbols give.
Expression:
ΔU = ________
Part (b) Find the numerical value of the change of the electrical potential energy in electron volts (eV).
Numeric: A numeric value is expected and not an expression
ΔU = __________
