A glass rod becomes positively charged when it is rubbed with silk. This net positive charge accumulates because the glass rod

• gains electrons

• loses electrons

• gains protons

• loses protons

Rubbing the balloon on the sweater allows more electrons to move onto the balloon. This gives the ballon a ​ (a)   charge.

• negative

• positive

• neutral

• powerful
