Your physics assignment is to figure out a way to use electricity to launch a small 6cm long plastic stirrer You decide that you will charge the little plastic rod by rubbing it fur then hold it near a long charged wire When you let go the electric force of wire on the plastic rod will shoot it away Suppose you can uniformly charge the plastic stirrer to 10nC and that the linear charge density of the long wire is 10 7 C m The mass of plastic stirrer is 1kg OM 12 The electric force on the plastic stirrer if the end closest to the wire is 2cm away is A 4 2 10 N B 2 8 10 N C 1 4 10 N D 8 5 x 104N
