CHOOSE CORRECT/INCORRECT FOR EACH OPTION

Electric Field Lines and Potential The figure shows the E-field in the plane of two point charges. Determine for each of the following statements whether it is correct or incorrect. 2 The E-field at 'c' points west. The magnitude of the E-field at 'a' is larger than at 'd'. The net charge Q1+Q2 is positive. The electric potential (volts) is larger at 'e' than 'd' The E-field at 'b' points directly toward Q2 The E-field at 'c' is zero. Submit Answer Tries 0/15

Explanation / Answer

1. correct

because the tangent at c gives the direction of Electric field at c which is towards west.

2. wrong

because electric field is maximum near the charges.

3. wrong

because it may be positive, negative or zero. we cannot conclude it from the figure.

4. correct

because the line of Electric field is towards radially to the negative charge and outwards radially to the positive charge.

5. wrong

because there is some electric field at c.
