Answer:
Resistivity of both wires are same
Explanation:
Length of one wire,
Diameter,
Radius,
Temperature in each case is same.
Area of each wire,
Resistivity is the property of material due to which it offers resistance to the flow of current.
Resistivity of material depends upon the temperature and material by which it is made.
It does not depends upon the length of object.
Therefore, the resistivity of both wires of different length are same.
Answer:
The distance of separation is
Explanation:
The mass of the each ball is
The negative charge on each ball is
Now we are told that the lower ball is restrained from moving this implies that the net force acting on it is zero
Hence the gravitational force acting on the lower ball is equivalent to the electrostatic force i.e
=>
here k the the coulomb's constant with a value
So
