Figure $2$ shows two L$-$shape objects that placed on the horizontal $xy-$plane. A uniform magnetic field is directed into this plane $(-z$ direction$).$ Initially, at $t=0,$ the corners of the L $-$shape objects $($points C and D$)$ coincide. As shown in Fig. $2$ one object remains stationary while the other is pulled at corner $C$ with a velocity $v$ at angle $$ above the $+x$ axis. Cucullate the induced emf if $B=5\mathrm{.}0mT,v=0\mathrm{.}5\frac{m}{s}$ and $=45.$ Determine the current and its direction in the loop if resistance per unit length is $r=45\mathrm{.}0\frac{}{m}.$ Indicate the direction of current on Fig. $2.$ure $1$ shows a positively charged particle $q$ is at a distance $r$ from a straight wire carrying a current I in the $+x$ direction. The particle moves with a velocity of $v$ at angle $$ above the $+x$ axis. Find the magnetic force acting on the particle. Identify a location at the same distance $r$ where a negative point charge $-Q$ can be placed to produce an electric force on the particle in the direction opposite to the magnetic force. Calculate the net force on the particle. Assume I$=5\mathrm{.}0$ A$,q=2\mathrm{.}0C,Q=200\mathrm{.}0C,r=2\mathrm{.}0cm,v=20\mathrm{.}0\frac{m}{s}$ and $=30.$
