1.	A cylindrical copper conductor AB length `L` areaa of cross-section a has large number of free electrons which at mean temperature move at random within the body of the conductor like the molecules of a gas. The average thermal motion at room temperature is of the enter of `10^(5)ms^(-1)` where a potential difference `V` is applied free electronic in the condictior experience , the free electrons in the conductor experience force and are accelerated towards the positive emf of the condutor on their gained kinetic energy After each collision the free electronic are angle acceleration due of the electric field , towards the positive end the conductor and next collision with the ions/atoms of the electrons The average speed of the free electrons with which they drift toward the positive and of the conductor under the effect of applied electric field is called drift of the electrons The motion of electrons in between two successive collisions with the atoms/ions followsA. a straight pathB. circular pathC. elliptical pathD. carved path
Answer» Correct Answer - d The free electrons moving toward the position end of the condoctor have two types of velocities (i) thermal velocity (ii) velocity due to the acceleration by virtue of force on it due to electric field. As result of it , the electron follow a curved path in between two collision in a conditor
