1. The problem statement, all variables and given/known data 10. If an electron is released from infinity, how fast will it be traveling after falling to within 10-8m of a charge q of 4.8*10-19? a. 1.32*104m/sec b. 8.7*104m/sec *c. 2.76*105m/sec d. 4.01*105m/sec 2. Relevant equations ΔU=ΔVq V=kq/r conservation of energy: 1/2mv2=Vq 3. The attempt at a solution 1/2mv2=Vq 1/2mv2=kqelectronq/r v=√(2*kqelectronq/r*m) v=√(2*9x109*1.602x10-19*4.8x10-19/(10-8*(9.11x10-31)) v=3.89x105 I get an answer not available in the options, the correct answer is supposed to be letter C what did I do wrong?
