Question

The picture shows the field lines of a nonuniform electric field and five points A to E in the field. Consider the following statements. Which one is true? The electric field strength at point B is larger than at point C. We cannot compare the electric field strengths at points E and C because they are not drawn on the same electric field line. The electric field strength at point C is larger than at point B. This electric field may be due to a negatively charged object located to the left. O A positive point charge placed at point C will feel an electric force pointing to the left. Submit Answer Tries 0/2

Answer 1

1) False
because, electric field strength is directly proportional to no of fields lines crossing per unit area.

2) False
Because, to compare electric field strength the two points need not be on the same line.

3) True
because, electric field strength is directly proportional to no of fields lines crossing per unit area.

4) False
Because, a negative charge produces electric field lines inward.

5) False
Because, a positive charge is always accelerated in the direction of electric field.

R_tot = R1 + R2

= 60 + 90

= 150 ohms

I1 = V/R_tot = 25/150 = 0.167 A

I2 = I1 = 0.167 A

V1 = I1*R1 = 0.167*60 = 10 V

V2 = I2*R2 = 0.167*90 = 15 V
