Solution To solve for the work done, first we must determine what is the final kinetic energy of the electron. By concept, we know that K=(1/2)mv²1 K2=(1/2)mv2 But it was mentioned that: v2=( V1 so, K2 in terms of v1 is K2=( )mv², Substituting the expression for K1 results to K2= K1 Since work done is W=AK=K -K Evaluating results to W=( K1
