When a glass rod is rubbed with a piece of silk cloth, then :
(a) the glass rod and silk cloth both acquire the positive charge.
(b) the glass rod becomes positively charged while the silk cloth has a negative charge.
(c) the glass rod and silk cloth both acquire the negative charge.
(d) the glass rod becomes negatively charged while the silk cloth has a positive charge.
A positively charged glass rod is touched with the disc of an uncharged gold leaf electroscope. What will be your observation?
If glass is a non conductor of electricity, then how does a positively charged glass rod produce a similar charge to neutral glass rod by touching it (which is theoretically called 'conduction') ??
