Question

The electron in the beam of a television tube moves horizontally form south to north.The vertical component of the earths magnetic field point down the electron is deflected towards

Answer 1

Explanation:

F=q(v×B)

Consider, v is acting in the south to north i.e. in the +y direction. The vertical component of B is in downwards direction i.e. −z. Hence v×B will be in −x direction. So, the beam will get deflected towards west.
