... You are helping to design a new electron microscope to investigate the structure of the HIV virus. A new device to position the electron beam consists of a charged circle of conductor. This circle is divided into two half circles separated by a thin insulator so that half of the circle can be charge ...

... the particles are sufficiently far apart so that the only force acting on each particle after it is released is that due to the electric field. At a later time when the particles are still in the field, the electron and the proton will have the same (A) direction of motion (B) speed (C) displacement ...

... If you ask a random collection of first year students, “What do you know about relativity?” the answers might be: “All is relative?” “It all depends on your frame of reference.” “You will never measure an absolute velocity unless you look into space.” “Wasn’t it invented by the same guy that gave us ...

... Multiple choice are 5 pts each 2) Two point charges Qa and Qb are placed a distance d apart. The electric field is zero at a point P between the charges on a line segment connecting them. Which of the following is true? a) Qa and Qb must have the same magnitude and sign. b) Qa and Qb must have the ...

... 152. How does the magnitude of electrical force between a pair of charged objects change when the objects are moved twice as far apart? Three times as far apart? 153. How does the magnitude of electric force compare between a pair of charged particles when they are brought to half their original dis ...
