Explanation:
It's pressure become three times larger because according to Boyles Law the pressure of fixed mass of gas is inversely proportional to it's volume provided that temp remains constant. That means a reduction in volume, will result in an increase in pressure and vice versa.
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.

<span>Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.</span>
