Electrostatics is a branch of physics which deals with the study of forces , fields and potentials from static charges.
Eg. -The experience of hearing or seeing a spark while removing our synthetic shirt or nylon sweater usually in dry weather.
-The sensation of electric shock while opening the door of any car.
-The sensation of shock while holding an iron bar of a bus after sliding from our seat.
-The metallic bodies cars and trucks get charged due to friction between them and the air passing swiftly rubbing them.This charge can even produce an spark.
SOLUTIONS - Petrol tankers usually have a metal chain dragging along the ground.This chain transfers the excess charge on the body to ground.
-Now-a-days a carbon compound is added to the rubber tyre.It discharges the excess charge if any to the earth.
