Question

A conducting rod PQ is moving parallel to X-axis in a uniform magnetic filed directed in negative z-direction. The end P of the rod will become​

Answer 1

$\huge{\bf{\blue{\fbox{\underline{\color{red}{Answer }}}}}}$

Force of positive charges in rod = q v×b

As v is along x axis and B is along y axis the force will be along the z axis. Therefore the positive charges will move towards the end P and it will become positive charged.

Answer 2

Answer:

Force of positive charges in rod = q

v

×

B

As v is along x axis and B is along y axis the force will be along the z axis. Therefore the positive charges will move towards the end P and it will become positive charged.
