In a uniform electric field, equispaced equipotential surfaces have equal change in potential

• True

• False

• May be true

• Cannot be determined

Electric field lines are

• Perpendicular to the equipotential surface

• Inclined with the eqipotential surface

• Alone the equipotential surface

• Incline if the core potential surface is curved.

1C Charge is moved from A equipotential surface to B equipotential surface as shown figure.Electric field is

• 50 V/m

• 0.5V/m

• 2V/m

• 100V/m
