The electric potential varies in space according to the relation V = 3x + 4y. A particle of mass 10 kg starts from rest from point (2, 3.2) m under the influence of this field. Find the velocity of the particle when it crosses the x-axis. The charge on the particle is + 1 μ C. Assume V (x, y) are in SI units.
