When do we use this equation for?

This question falls under Heisenberg uncertainty equation so I'll answer based off of that. This equation shows the relation between both the uncertainty in momentum as well as the uncertainty in position. It exhibits complementary which means that if one is known, the other can not be. This is due to wave-particle duality. If the uncertainty of position is small, then there will be a larger uncertainty in momentum.

In addition to Brianna Becerra 1F, you would typically use this equation when being asked for the minimum uncertainty in speed/velocity when given the physical constraints or vice versa.

Is minimum uncertainty something different or when we solve this equation we get minimum uncertainty?

Minimum uncertainty just means that you assume that h/4pi is equal to the uncertainty, since the equation is actually greater than or equal to.
