The diagram at the right shows a metal sphere attached to the top of an insulating standthe metal sphere contains an excess of electrons and is thus chargeda student holds various objects in her hand and touches the object to the spherewhich of the following objects below would allow charge to throw it when the student touches the object to the sphere?aa plastic strawba piece of paperca steel house keyda metal paper clipea strip of aluminum foilThe diagram is just a circle with 12 quot;-quot; circling the inside
Get him a grammar lesson and one on manners.
I'm a little confused by your questionWhat exactly do you mean by throw it? Although I am not sure of it, I assume you are asking what will repel the object when contact is made with the negatively charged sphereSince opposite charges attract and similar charges repel, the object touching the negatively charged sphere would have to also be negatively chargedView the Triboelectric Series Table at the source link I posted belowThere you will see that aluminum and paper loose electrons to become positively charged and steel (metal) is neutral, while PVC (plastic) attracts electrons to become negatively charged.
I would laugh and walk away.
