Hi there,
I am thinking about a problem here,
A particle q produces an electric potential of 6.30E2 V at a distance of 1 m away. If a particle of charge Q=0.00300 C is released from rest at a distance of 8.00 m from q, what will be its kinetic energy after moving very far from q?
My question is, can I use the work-energy theorem here? As in
Ki + Ui = Kf + Uf ?
If I choose a point at 8.00m, then the Ki will be zero, am I right? Then Ui would be Ui = Vi/Q, is this the right equation to use? And then at infinity or very far away, Uf will be zero too. Is this the right approach?
Need help...thanks in advance
