The electron near the Earth's equator doesn't deflect if it's velocity is directed downwards.

Assume that north is directed along upwards, south is directed along downwards, east is directed along rightwards, and west is directed along leftwards.

The magnetic force on the charge q, moving with velocity v in the magnetic field B is given by

F=q(→v×→B)=qvBsinθ ..(1)

Here,

θ is the angle between the magnetic field and velocity.

Inside the Earth, the Earth's magnetic field is along northward (upwards), and the velocity is given to be along southwards (downwards) making an angle of 180°. In equation (1) sin180°=0. So, no magnetic force acts on the electron

Therefore,

The electron didn't deflect if it is directed downwards.

Every 4 years we have a leap year on our calander to make up the extra.......
OverLord2011 [107]

The Earth takes very nearly (365 and 1/4) days to go around the sun.

If our calendar always had 365 days, then the year would end and re-start
too soon, and the beginning of Spring (and every other season) would
eventually drift into the months after March.

If our calendar always had 366 days, then the year would end and re-start
too late, and the beginning of Spring (and every other season) would
eventually drift into the months before March.

We can't make calendars with an extra quarter-day in each year.  But we
keep them lined up with the real year by saving up the quarters, and adding
one full day to the calendar every 4 years.
