Q1 : In the figure, the three particles are fixed in place and have charges C Q 2 1 , C Q 1 2 and C Q 1 3 . Distance a = 4cm. What is the net electric field at point P due to the particles? Q2 : Three charges, q 1 = -2 C, q 2 = 1 C, and q 3 = 3C, are placed on the xy -plane, as shown in the figure. The coordinates of q 1 , q 2 , and q 3 are respectively given as (0, 4m), (3m, 0), and (3m, 4m). Calculate the electric field at the origin in unit vector notation . y q 1 q 2 q 3 x O

Q3 : Figure shows two concentric rings, of radii R and R =3R, that lie on the same plane. Point P lies on the central z axis, at distance D=2R from the center of the rings. The smaller ring has uniformly distributed charge +Q. In terms of Q, what is the uniformly distributed charge on the larger ring if the net electric field at P is zero? Q4 : Charge is uniformly distributed along the rod with nC 5 q 1 in the upper half and nC 5 q 2 in the lower half. If m 6 L and
