Unformatted text preview: 1 =70 V and V 2 =50V. The particle is slowing from initial speed of 90 km/s at the left plate. a) Is the particle an electron or a proton? b) What is its speed just as it reaches plate 2? Q6 : In figure, point P is at distance d 1 =4 m from particle 1 (q 1 =2e) and distance d 2 =2 m from particle 2 (q 2 = +2e), with both particles fixed in place. a) With V=0 at infinity, what is the potential at P? b) If we bring a particle of charge q 3 =+2e from infinity to point P (i) How much work do we do? (ii) What is the potential energy of the threeparticle system? Q7: Over a certain region of space, the electric potential is V = 5x – 3x 2 y + 2yz 2 . Find the expressions for the x, y, and z components of the electric field over this region. What is the magnitude of the field at the point P, which has coordinates (1, 0, 2) m?...
