Question

art the simulation on that page. The display should look like Figure 1 below. Note that you can move the lloon on screen by clicking and dragging it with the mouse. Let each red positive dot count as an ion with a St balloon on screen b charge of "+1." Let each blue negative dot count as an ion with charge "-1." 004 oaoc ® Show al charges O Show no chargers O Show charge differences Remove Wal Reset Baloon Figure 1: PHET Simulation Display 1. Initially, what is the NET CHARGE on... a. The sweater? b. The balloon? c. The wall? Using the mouse, move the balloon to the left and rub it against the sweater. Look for ions that move. 2. What is the new NET charge on the balloon? (Give a sign and number, e.g."+5") 3. What is the new NET charge on the sweater? 4. If we let the "system" be the balloon, then does this simulation demonstrate the conservation of charge? Explain.

Explanation / Answer

I am unable to see coloues so cant tell net charge on any one: balloon,sweater etc.
As you can, just add1 for positive, subtract 1 for negative charge.

Seater is conductive material and thus, gives away electrons(the negative charges) so considering all are electri ally neutral earlier, sweater looses negative, become more positive and balloon gets negativelt charged.

This tells that, charges can only travel from one body to another, and cannot be produced or disappeared.
