Tyo point eharges \( a \) and \( b \) whose magnitudes are same positioned at a certain distance along the positive x-axis from each other. \( a \) is at origin. Graph is dravn between electrical field stremgth and distance \( x \) from a. \( E \) is taken positive ifit is alomg the line joining fiom a to b. From the grapl it can be decided that :
Figure 1.367
(A) \( a \) is positive, \( b \) is negative (B) a and b both are positive
(C) \( a \) and bboth are negative (D) a is negative, bispositive
