Question

Q.34 The variation of electric field between the two charges q1 and q2 along the line joining the charges is plotted against distance from q1 (taking rightward direction of electric field as positive) as shown in the figure. Then the correct statement is Choose answer: q1 and q2 are positive and |q1| > |q2| q1 and q2 are positive and |q1| < |q2| q1 is positive and q2 is negative |q1| < |q2| q1 is negative and q2 is positive |q1| > |q2|

Answer 1

Answer:

Since field is changing it's direction, this means both charges have same sign. Also note that field near q1 is positive, this means q1 should be positive(since field is away from charge if charge is +ve). Also equilibrium position(point where field is zero) is near q1, this means q2 > q1.
