A system is in stable equilibrium. What can we say about its potential energy?

Read the following paragraph and answer the questions given below , Stable equilibrium is of various type . Mechanical equilibrium is achieved when all particles are at rest and total potential energy of the system is minimum . At any stage where particles are at rest but the system is not at stabel equilibrium as it can reduce its potential energy by reverting to another position, is called metastable equilibrium . Thermal equilibrium is result from the absence of temperature gradients in the system. chemical equilibrium is obtained when no further reaction occurs between reacting substances, i.e forward and reverse rates of reaction are equal. when steam with solid iron at high temperature Fe_3O_4(s) and hydrogen gas are produced . But the reaction never goes to completion. this is because as the products are formed the reaction proceeds in reverse direction and when rate of reverse reaction is equal to rate of forward reaction , the concentration of reactants and products become constant and equilibrium is reached. The primary objective of the passage is

A point is in the XZplane.What can you say about its ycoordinate?

The bola is a weapon used by gauchos for entangling animals. It consists of three balls of stone or iron connected by things. The gaucho whirls the bola in the air and hurls it at the animals. What can we say about its motion?

Assertion :Mean positon of SHM is the stable equlibrium position. Reason: In stable equilibrium , position potential energy is minimum.

Statement I : For the stable equilibrium force has to be zero and potential energy should be minimum. Statement II : For the equilibrium it is not necessary that the force is not zero.

STATEMENT - 1 : Potential energy has a minimum at the position of stable equilibrium. ltbgt STATEMENT-1: Potential energy has a minimum at the position of stable equilibrium. STATEMENT-2: Mechanical energy of a system is always positive STATEMENT 3-: Work done by the friction may be positive identify the correct combination of true (T) and false (F) of the given three statements

When gravity is the only force doing work on a body, what can we say about its energy ?

When dipole moment vec(p) of a dipole is parallel to electric field intensity vec(E ) (stable equilibrium) the potential energy of dipole is
