a)
From work energy
work done = change in potential energy
therefore,
the difference between the electric potential energy of charge at two points =6.40*10^-3 J
b)
delta K = Kf - Ki
but Vf=Vi
so, delta K = 0 J
c)
delta U =q*delta V
delta V= delta U/(q)
= 6.40*10^-3 J/(2.20*10^-6 C)
= 2909.090909 volts
delta V = 2909 volts
d)
point A is at higher potential than B.Since it requires positive work to move the negative charge from A to B.

A particle with a charge of -1.3 uc and a mass of 2.2 x 10-6 kg is released from rest at point A and accelerates toward point B, arriving there with a speed of 37 m/s. The only force acting on the particle is the electric force. (a) Which point is at the higher potential? point A point B Give your reasoning. Negative charge accelerates from a lower potential to a higher potential. Negative charge accelerates from a higher potential...
