106If it is an isolated body then it is true..
But not true for a system.
See this for example

True /false
When a body is coonencted to earth all the charge flows to eart and it becomes electrically neutral..
ans is true..
but all the charge doesnt necesarily flow acc to me..
am i rite or wrong...tell me...

11Yeah
If a conductor is connected to the earth, the potential of the conductor becomes equals to that of the earth, i.e, zero. (Potential of earth is often taken as zero).
If the conductor was at some other potential, charges will flow from it to the earth to bring it's potential to zero.
Suppose two identical metal plates having charges q1 and a2 are placed facing each other at some seperation, and if we join the right (second) plate with the ground, then the charge appearing on the outer surface of the right plate will go to the earth.
Any metal object connected to earth need not to have zero charge. If a conductiong bodyis isolated to the earth, it will have no charge. If the conducting bodyis connected to the earthhave any charged object near it to the bdy will not have zero charge,.
11i had this doubt too..
see the fiitjee q i had posted..asish has given the link.
3earthing is just like connecting a charged object having some potential V with another object having an infinite capapcity to accept or donate electrons.is dat rite.
