There is an intrinsic magnetic moment of the proton. Its small magnitude is one of
reasons leading scientists to know that the proton is not an elementary particle but it
consists of something we call quarks. But this intrinsic magnetic moment gives a proton
some particular property. Which is it? - ANSWER-polarity
Electrical current is: - ANSWER-a flow of charges
Which statement is wrong? - ANSWER-electrons consist of two quarks where one
quark is having negative charge -1 and other quark has charge equal to 0. In particle
physics they are called leptons and when a quark undergoes annihilation, electron
becomes a positron.
Point A is at lower electrical potential than point B. An electron between them on the line
joining them - ANSWER-will move towards B.
