Suppose an electron (q= -e= - 1.6 x 10-19 C,m=9.1 x 1031 kg) is accelerated from rest through a potential o-31 difference of Vab = +5000 V. Solve for the final speed of the electron. Express numerical answer in two significant figures. The potential energy U is related to the electron charge (-e) and potential Vab is related by the equation: U= Assuming all potential energy U is converted to kinetic energy K, K+U=0
