Suppose an electron (q = – e= -1.6 × 10¬19 c,m=9.1 × 10¬31 kg) is accelerated from rest through a potential 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 K = -U 1 -mv² and using the formula for potential energy above, we arrive at an equation for speed: Since K=
