nderstanding what is the logic behind his marked part answer should be simply by the formula of electric field for infinit od but how they applied concept of yperbola lease help me hank you 1 03 pm 2 Which of the following graph shows curve between electric field E versus distance r from infinite line charge having constant positive charge density A B C D Solution D We know that due to infinite line charge of constant linear charge density A En 0 and E Enet So Enct E E Constant T 2kX Entr constant T since k and are constant zy constant 2kX T On taking Enet at y axis and r at z axis we get This is the equation of rectangular hyperbola Therefore the curve between E and r is a rectangular hyporhola 03m 31 S 88
