Question

An object will be stable if __________.

Answer 1

Answer:

option (b)

Explanation:

An object is said to be in stable equilibrium if its potential energy is minimum and the force acting on the object is zero.

When the base of an object is too broad so that the vertical line passing through its centre of gravity line passes though this base, it is said to be in stable equilibrium. \

Thus, option (b) is correct.

Answer 2

Answer:b

Explanation:

Object will be stable if its center of gravity lies over its base of support.

If the center of gravity is above the center of buoyancy then it provides positive righting moment and the object floats over the liquid and such object is said to possess positive meta-centric height.
