To establish equilibrium all torques need to be justified , the body needs to be in translational as well as rotational equilibrium.
<h3>What is equilibrium and why balancing the torques is not enough to establish equilibrium?</h3>
- Equilibrium is a condition of balance between forces, or influences from opposite ways .
- For a body to attain equilibrium , need to have both translational as well as rotational equilibrium.
- Force is responsible for translational equilibrium and torque is responsible for rotational equilibrium.
- Considering a rod , and applying equal forces at the ends of the rods in upward direction, and seeing the net torque to be zero.
- Hence the body needs to be in both translational and rotational equilibrium to attain equilibrium.

Answer:
A. The upward pressure gradient force is balanced by gravity.
Explanation:
A. is correct because the pressure difference is actually generated by gravity. As in the following formula for the pressure at different points:
where 
are the pressure at 2 points, ρ is the density of the fluid, g is the gravitational constant, and h is the height difference.
B is incorrect because friction in air is too small to make an effect.
C is incorrect because the Coriolis force is horizontal, not vertical.
D is incorrect because a difference of 500 hPa = 50000 Pa, this is half of the atmospheric pressure.
E is incorrect because temperature cannot generate force.
