Potential difference question...
A proton (mass = 1.67 10-27 kg, charge = 1.60 10-19 C) moves from point A to point B under the influence of an electrostatic force only. At point A the proton moves with a speed of 60 km/s. At point B the speed of the proton is 80 km/s. Determine the potential difference Image .
Vb-Va = 0
a) +15v
b) -15V
c) -33V
d) +33V
e) -20V
im stumped with this one...any help would be appreciated.
