What I personally would do is tear a strip from a sheet of nose- or toilet-tissue,
hang it next to the object under test but not touching it, and see if the paper is
attracted to the object. I call it the 'poor man's gold leaf'.
an electroscope is used to determine whether an object is charged or not. However, it will not tell if the object is positively or negatively charged.
I you touch it, and it shocks you, then it was statically charged.
Charge is induced in the object when another charged object brought near it. this happens due to charge separation in the object thus making it polar.
No.
If the object remains ungrounded it will remain charged.
Some ways in which an object can become charged are friction, contact and induction.
when a negatvely charged object touches a neutrally charged object electrons move to the neutraly charged object making it negativly charged!
There will be flow of electrons from negatively charged object towards the positively charged object making an attempt to make both of them electrically neutral.
A positively charged object. Like charges repel.
It depends on the type of non-charged object. If the object is made of conductive material, a charged object will induce a separation of charge in the non-charged object. Its net charge will still be zero. If the object is not conductive, there will be no significant effect.
When an object is charged, it either has a surplus or deficiency of electrons. If it has a surplus, the object is negatively charged, and if it has a deficiency, then it is positively charged (has more protons than electrons).
A negatively charged object. Also, a neutral object, through an induced separation of charges.
