and Fields And a second charge q2 is similarly placed at a distance 58 12 1 on the opposite side of circle 2 Choose the correct answer A 9 If the net flux through circle is zero then would be 3 Circle of radius 8 cm 4 Circle of radius 4 cm 1 2 14 2 1 a If the value of q and q are 100 C and 400 C respectively and they are separated by a distance of 30 cm The locus of all points in the plane where electric potential is zero would be 14 2 1 1 Straight line 2 Parabola whose axis is line joining the charges cm cm 2 3 If the values of q and q are q 2q respectively now a third charge q has to be placed on line AB so that it can be in stable equilibrium The distance of point where third charge is placed from charge q would be take a 12 cm 4 cm 13 20 9 B 2 9 2 R 91 92 14 3 2 2 1 44 q cannot be in stable equilibrium at any point Comprehension 1 A spherical shell of inner radius R and outer radius 2R has a uniform charge distribution and total charge Q Choose the correct answer 1 2 3 The charges inside the Gaussian sphere for given three regions are respectively 1 0 a R R a 2R ii 2R a 1 0 2 0 3 0 Q 2 0 1 0 a R ii R a 2R 2R a are respectively 1 0 3 0 4 0 4 0 Q Use Gauss s Law the electric fields at the surfa of the Gaussian surface when Q 28ma 25ma Q 32me a 1 3 E Q 30mega 4nEr 3 Q 2Q Comprehension Ill Q 4Q R BR R 3 2 3 Q Q 2me a Q 47 a The electric field in a region of space is E E The flux of electric field through a sphere of radu r centred at origin is Q 41 0 JEE Cha 1 2 E 4 Zero For a uniformly charged disc of radius R and surface charge density a centred at origin and
