A material is said to be ductile if it can be stretched thin when tensile stress is administered. Such a material can be stretched into a wire.
This is different from malleability which describes a material that can bend or alter shape using compressive force e.g. hammering , rather than tensile stress.
Tensile stress is a type of force or stress that alters the length of a material in the same direction as the force being applied.
The opposite of ductile is brittle. Brittle materials can break when subjected too much tensile stress.
Answer:
qn is wrong pe= mgh but there is no height
As the plastic sphere is charged, therefore it experience an electric force when placed in an electric fields and also experiences gravitational force acts downward so the electric force must act upward.
Let is electric force and is gravitational force.
If these forces are balanced, therefore
or
Given, and .
Substituting these values in above equation we get,
Thus, the magnitude of electric field is .
As the charge is negative, the electric field at the location of the plastic sphere must be pointing downward.
