A uniform electric field of magnitude $5 \mathrm{x} {10}^3 \mathrm{N}/\mathrm{C}$ is directed along the negative x-direction. Co-ordinates of point A in the Fig. 2.134 are (-40 cm,+ 20 cm) and those of point Bare (20 cm, -60 cm). Potential difference between A and B, i.e., ${\mathrm{V}}_{\mathrm{A}}-{\mathrm{V}}_{\mathrm{B}}$ along the arc of a circle of radius 2 m is :

• A

  2400 V

• B

  -5000 V

• C

  -2400 V

• D

  -3000 V
