# BOUYANCY FORMULA FOR FLOATING OR SUSPENDED (BALANCED IN FLUID) OBJECTS

Think about an object floating in a water. There are two forces acting on the object in this case which are upthrust of water and weight of the object. These two forces must be equal so that the object can float in the water.

To select a light bulb very first step is defining the need for lighting. The lighting is categorised into two sections which are ambient lighting and task lighting.
