The diagram shows an electron in a uniform electric field.
In which direction will the field accelerate the electron?

Which statement about electric charges in a uniform electric field is not correct?

If the potential at each point on a conductor is same to each other, then

For the metallic conductor.

If two charged particles of same mass and charge are projected in a uniform electric field with the same speed, then

Identical charges of magnitude $$Q$$ are placed at $$(n - 1)$$ corners of a regular polygon of $$n$$ sides each corner of the polygon is at a distance $$r$$ from the centre. The field at the centre is

A hollow sphere of charge does not produce electric field at any

Two identically charged spheres when suspended by strings of equal lengths make an angle of $$30^{\circ}$$ with each other. The angle remains the same when they are immersed in a liquid of density less than the density of the material of the spheres. Choose the correct option

Coulomb's law is applicable to
