3. A positively charged particle with the charge of +5e and a certain mass is moving with the initial velocity v. into the region of the uniform electric field. The particle moves from point a to point b through a potential difference 4V=V -V., as shown in Figure. The particle has a final velocity of vevo. Is it moving from higher to lower potential or from lower to higher potential? Find the mass of the particle in terms of e. V, v. and ve. Va b E
