Answer:
In the absence of electric field the path of electrons are straight lines between successive collisions. ... Therefore, in the presence of electric field the electrons follow a curved path in between successive collisions. Consider a conductor of length'l' and of uniform area of cross section 'A'.

Answer : When electrons move between two collisions, their paths are A, when external fields are absent and B when external filed is present. A and B are (b) straight lines, curved lines.
Explanation:
In conductor ,
- When electrons move between two collisions, their paths are straight lines when external fields are absent.
- When electrons move between two collisions Paths are curved in general when external field is present .
Hence, when electrons move between two collisions, their paths are A, when external fields are absent and B when external filed is present. A and B are (b) straight lines, curved lines
