When a plastic rod is
rubbed with wool, the wool acquires a positive charge because electrons
are transferred from the wool to the rod protons
are transferred from the wool to the rod electrons
are transferred from the rod to the wool protons
are transferred from the rod to the wool 2.
Conductivity in metallic solids is due to the presence of free
nuclei protons
neutrons
electrons 3.
If a positively charged rod is
brought near the knob of an uncharged electroscope without touching it, the leaves will
diverge because negative
charges are transferred from the electrocope to the rod negative
charges are attracted to the knob of the electroscope positive
charges are repelled to the leaves of the electroscope positive
charges are transferred from the rod to the electroscope 4.
When a positively charged body
touches a neutral body, the neutral body will gain
protons lose
protons gain
electrons lose
electrons 5.
If object A becomes positively
charged when rubbed with object B, then object B has gained
electrons lost
electrons gained
protons lost
protons 6.
Why does a neutral hard rubber
rod become negatively charged when rubbed with wool ? The
rod loses protons The
rod loses electrons The
wool loses protons The wool
loses electrons 7.
When two objects are rubbed
together, which particle is most likely to be tranferred ? nucleus
electron
proton
neutron
8.
A neutral object can become
positively charged by gaining
electrons losing
electrons gaining
protons losing
protons 9.
As a negatively charged rod is
moved toward the tip of a positively charged electroscope, the number of electrons in the
tip of the electroscope decreases
increases
remains
the same 10.
As charged body A charges
neutral body B by direct contact, the quantity of charge on body A is
decreased is
increased remains
the same 11.
In general, solid materials
become electrically charged because of transfer of positrons
electrons
protons
neutrons
12.
A neutral pith ball suspended
on a string is attracted to a positively charged rod. During contact with the rod, the pith ball loses
electrons gains
electrons loses
protons gains
protons 13.
If a positively charged rod
touches a neutral metal sphere, the number of electrons on the rod will decrease
increase
remain
the same 14.
A positively charged rod is
held near, but does not touch the knob of a neutral electroscope. The charge on the knob becomes positive
and the leaves become positive positive
and the leaves become negative negative
and the leaves become positive negative
and the leaves become negative 15.
When two neutral materials
are rubbed together, there is a transfer of electrical charge from one material to the other. The
total electrical charge for the system increases
as electrons are transferred increases
as protons are transferred remains
constant as protons are transferred remains
constant as electrons are transferred
