Consider two objects A and B. Object A has a net charge while B is uncharged. Based on this information,
it must be true that correct answersE. There's not enough information to tell.
Charged glass and plastic rods hang by threads. An object attracts the glass rod. If this object is then held
near the plastic rod, it will correct answersD. Either A or B. There's not enough information to tell.The
object could have plastic charge, which would repel the plastic rod. Or it could be neutral and attract
both charged rods.
A rod attracts a positively charged hanging ball. The rod is correct answersE. Either B or C.
Metal spheres 1 and 2 are touching. Both are initially neutral.a. The charged rod is brought near.b. The
charged rod is then removed.c. The spheres are separated.Afterward, the charges on the sphere are:
correct answersE. Q1 is 0 and Q2 is 0
Metal spheres 1 and 2 are touching. Both are initially neutral.a. The charged rod is brought near.b. The
spheres are separated.c. The charged rod is then removed.Afterward, the charges on the sphere are:
correct answersQ1 is − and Q2 is +
Net charge is obtained if contact is broken while the spheres are polarized. This is charging by induction.
Based on the last experiment, where two spheres were charged by induction, we can conclude that
correct answersD. We can draw no conclusion about which charges move.
Identical metal spheres are initially charged as shown. Spheres P(+4) and Q(-2) are touched together and
then separated. Then spheres Q and R(-1) are touched together and separated. Afterward the charge on
sphere R is correct answers0 nC
The charge of sphere 2 (medium sized right arrow) is twice that of sphere 1. Which vector below shows
the force of 2 on 1? correct answersleft medium sized arrow (newtons third law)
, The charge of sphere 2 (medium sized right arrow) is twice that of sphere 1. Which vector below shows
the force of 1 on 2 if the distance between the spheres is reduced to r/2? correct answerssmall, medium,
large right arrows but none are correct need XL arrow
Which of the three right-hand charges experiences the largest force? correct answersq (1+) and 4q(4+)
are tied (coloumbs law)
In each of the following cases, an identical small, positive charge is placed at the black dot. In which case
is the force on the small charge the largest? correct answers2q, r with small arow, black dot at right end
In each of the following cases, an identical small, positive charge is placed at the black dot. In which case
is the force on the small charge the largest? (All charges shown are of equal magnitude.) correct
answers+ ⦿ -
The direction of the force on charge −q is (+⦿+Q, -⦿-Q -⦿ -q small) correct answersRight. (−Q is slightly
closer than +Q)
Which is the direction of the net force on the charge at the lower left? correct answersB
Which is the direction of the net force on the charge at the top? correct answersD
Which of the two sets of electric field vectors is possible? correct answersBoth A and B are possible.
At which point is the electric field stronger? correct answersPoint A
Rank in order, from largest to smallest, the magnitudes of the electric field at the black dot. correct
answers3, 1, 2, 4
All charges shown have equal magnitudes. For cases 1 through 4 shown, is the electric field at the dot to
the right (R), to the left (L), or zero (0)? correct answerscase B: L, R, L, 0
