A 4.0g object carries a charge of 20uC. The object is accelerated from rest through a potential difference, and afterward the ball is moving at 2.0 m/s. What is the magnitude of the potential difference?
I know i have to use the law of conservation
Potential_initial + KE_initial = Potential_final + KE final
Potential_initial + 0 = 0 + KE final
but I don't know what to do after this. can some one give me any pointers?
