Choose the correct option

Options

A. A charged particle in an electric field always experiences a force either it is at rest or in motion and the direction of force is that of field if it is `+ve` ,and opposite to the field if `-ve`
B. (i) For an external point (i.e., `r gt R`) , a solid or hollow , conducting or non-conducting charged sphere behaves as if whole of its charge is concentrated at its centre.
(ii) In case of a hollow or solid conducting sphere for an internal point (i.e.,`r lt R`) , intensity `vec(E )` everywhere is dame and equal to zero
C. In case of spherical volume distribution of charge intensity an internal point `(r lt R)` will be due to the charge obtained in the sphere of radius `r`
D. All options are correct
