solutions
like charges..... (repel/attract) - answer repel


opposite charges....(repel/attract) - answer attract


positively charged objects________electrons -
answer lose


negatively charged objects_________electrons. -
answer gain


what charges are these objects?
- an object has more protons than electrons
- an object which attracts a negatively charged
balloon and neutral paper
- an object repels a balloon but repels a positively
charged balloon
- an object around with the electrical field is
directed outwards

, - An object which attracts a balloon (balloon C)
which is repelled by a negatively-charged balloon
(balloon D).
- An object which attracts a charged balloon
(balloon A) which is attracted to a negatively-
charged balloon (balloon B). - answer positive


what charges are these objects?
- A formerly neutral object that just gained some
electrons.
- An object which attracts neutral attracts paper
bits and repels a negatively-charged balloon.
- An object which attracts neutral attracts paper
bits and repels a negatively-charged balloon.
- An object around which the electric field vector is
directed inwards. - answer negative


What charges are these objects?
- An object which attracts a negatively-charged
balloon.
- An object which attracts a negatively-charged
balloon and attracts a positively-charged balloon.
- An object which attracts a charged balloon
