Electrostatic induction – Where does the charge go on earthing?

Rajkumar asks:”in electrostatic induction in step 3 when earthed wire is removed then where the free negative charge go.does they go to earth then what happen to them.” Waiting for responses from visitors Incoming search terms:earthing whic...

Variation of acceleration due to gravity with depth. A doubt.

Rajkumar asks: “accelaration due to gravity decrease on depth of earth with the relation of g’=g(1-2h/R). but with relation of g=GM/(R*R)  g increase. Answer: When the object is on the surface or above it, the entire mass of the earth attracts it. But when it is inside, the net attraction towards CENTRE is provided only by the mass of [...]
