357997 When a charge is given to a conductor

1 More charge accumulates at regions of small curvature
2 More charge accumulates at regions of large curvature
3 Charge is distributed uniformly irrespective of curvature
4 None of the above is true

1 Bend away from the wall due to the electrial repulsion between the electrons in the rubber and the charges on the wall
2 Bend towards the wall due to the polarisation of the rubber molecules by charged wall
3 Not be affected by the charged wall because the rubber sheet has zero net charge
4 Not be effected by the charge on the wall since rubber is an insulator
