To modify the units there is a consistent set of pre xes.
Three charged marbles labeled.
Q1 q3 b if the magnitude of the charge on q1 is 8 8 muc what is the magnitude of charge on q3.
Expressed in terms of three basic units.
B what is the magnitude of the force on a 1 1 µc charge placed at this point.
Answer to three charged marbles labeled q1 q2 and q3 are oriented such that q2 is between q1 and q3.
Q2 is also positive and is 2 cm away from q3 which is negative.
Other units can be built out of these.
The charge on q2 is 14 5.
What is the electrical potential at point p relative to infinity due to these charges.
However you re told that each of the labels are wrong.
Which box should you remove a marble from to determine the contents of all three boxes.
A what is the electric field at a point 1 0 cm to the left of the middle charge.
The charge on q is 13 9 pc.
91 93 and have what sign of charge.
You may reach into one of the boxes and pull out only one marble.
Three charged marbles are glued to a nonconducting surface and are placed in the diagram as shown.
Pre x meaning nano.
Q1 is positive and is 3 cm away from q2.
For ex ample the si unit to measure the ow of water through a pipe would be kg s.
Three point charges of 2 00 μc 4 00 μc and 6 00 μc are placed along the x axis as shown in the figure.
K 1 4πε0 8 99 109 n m2 c2.
Three charged marbles labeled and are oriented such that q is between q and gg.
Three closed boxes have either white marbles black marbles or both and they are labeled white black and both.
The charge on q2 is 14 8 muc.
The me ter m the kilogram kg and the second s.
Consider three charges q1 6 0 µc q2 1 8 µc and q3 2 8 µc arranged as shown below.
A q1 and q3 have what sign of charge.
The following are common and should be memorized.
