MCQ:When a negatively charged rod is brought near the cap of a gold leaf electroscope whose case is earthed,then
(i)leaves will have induced positive charge
(ii)Positive charge is induced
(iii)no charge is induced on the leaves
(iv) the leaf has an induced negative charge
Electric field at center of the cube will be zero, this is because diagonally opposite charges produces equal and opposite fields which cancels out each other.Electric potential at the center of the cube:
Vcenter = 8 X electric potential produced by any one of the corner charge
