Two point charges are situated symmetrically about the origin. The E -field measured at the origin is zero. At point P, the E -field points in the positive x- direction. From this one can conclude that: x P q 1 q 2 E 0 y [a] both charges are positive and equal in magnitude. [b] both charges are negative and equal in magnitude [c] the charges are of opposite polarity but of equal magnitude. [d] the charges are of opposite polarity and unequal magnitude. 1b .Two equal positive charges are situated symmetrically about the origin as shown. The net E -field at point P on the y-axis will point: + P x y o +q + +q [a] along the positive y-axis. [b] along the positive x-axis. [c] along the negative x-axis [d] The E -field at P is zero. 1c. A dielectric sphere of radius R is placed in a uniform electric field of magnitude E, as shown. The net electric flux through the sphere is equal to: R E [a] zero, [b] 4
