which of the following statements regarding static electric charge is most
accurate - ✔✔force is proportional to the inverse square distance between
the charged particles
An object has a positive net charge. The most likely reason for the net
charge is that - ✔✔electrons were transferred off the object
what is the net charge on an object that has gained 8x10^13 electrons -
✔✔8x10 ^13 * 1.6 x10^-19
=-1.3 x10^-5
which of the following processes will not result in a change in net charge on
an object? - ✔✔polarization
which of the following is an example of an insulation - ✔✔a piece of paper
a block of wax
a block of glass
all of the above are examples
,which of the following statements concerning charge is most accurate -
✔✔the total charge present in the system and surroundings is constant in
any process
Two charged particles both have positive net charges. They are near each
other and released from rest. Which of the following statements best
describes the interaction of the particles ? - ✔✔The particles will repel. As
they get further apart, the repelling force will decrease
Particle A has a net charge of -5uC. Particle B has a net charge +10uC.
Which of the following is the largest force? - ✔✔they apply the same force
on each other
Which of the following statements concerning the structure of an atom is
accurate? - ✔✔neutrally charged atoms contain equal amounts of protons
and electrons
Two identical metal blocks are in contact side-by-side. A positively charged
rod moves near the left block. Which of the following most accurately
shows the resulting distribution of charge throughout the metal blocks? -
✔✔When a positively charged rod moves near the left of the block, it
attracts or pulls negative charge of the block.
, a positively charged plastic balloon filled with air will stick to a neutrally
charged nonmetal ceiling. Which of the following is the most likely
explanation for this behavior? - ✔✔The ballon caused the ceiling to
polarize, which created a net attracting force between the polarized ceiling
and the balloon
an electroscope is a device that has small gold foil strips suspended from a
metal rod. If the electroscope is negatively charged, the foil strips will repel
and separate from each other. If you bring a negatively charged rod near
the top of a negatively charged electroscope, the foil strips will -
✔✔separate further
Which of the following is an accurate example of charging by induction -
✔✔a student brings a charged rod near a block of metal. The student taps
the block of metal with a hand and then removed the charged rod
Two charged particles each with a net charge of-q are a distance r apart.
The electric force F is measured The distance between the particles then
doubles to 2r and the amount of charge on both charges doubles to -2q.
Relative to the original force, what is the new electric force. - ✔✔F
