Okay, let us do some school level physics (what Arindam was taught in
Std 8)
Pressure is force/area.  (Fundamental school level education, useful in
hydraulics, which Arindam learnt in Std 9).
Force is a vector
Area is a scalar, when by convention its orientation is perpendicular to
the force.
The division of a vector by a scalar is a vector.
So pressure is a VECTOR.

The left side is a force, therefore (according to you) a vector.  None
of the quantities on the right side are vectors.  How does that happen?

 
You're missing the unit vector in the direction of the attracted to the
attractor.  Instead, you're only looking at magnitudes.
 
Forces always act in a direction, which means that they are described
by vectors.  Note that in case of gravitation, both parties are being
forceful.
