Answer is B) 1.00eV
Electrostatic force is a conservative force.Which means conservation of mechanical energy is valid.
=> P.E. + K.E. = same.
=> gain in kinetic energy= lost in potential energy =qV =e x 1.0V = 1.0 eV

How much work must we do on an electron to move it from point A, which is at a potential of +50V, to point B, which is at a potential of -50V, along the semicircular path shown in the figure? Assume the system is isolated from outside forces (e = 1.60 times 10^-19C) 1.60 times 10^-17 J -1.60 times 10^-17 J 1.6 J -1.6 J This cannot be determined because we do not know the distance traveled. If an electron...
