Ball made of wood and ball made of aluminum, of the same radius are placed into reservoir with water. aluminum ball after sinking rests at the bottom, wooden ball floats. which ball experiences greater buoyancy force? (14.4)

Aluminium

Explanation:

Given

Aluminium ball sinks after placing inside the water while wooden block floats.

Buoyancy on a body is given by

here

thus aluminium ball sinks

but for

only a part of wood is under the water i.e. not whole volume is not under water therefore net buoyancy is less in case of wood

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
