Resistance of a rod A is 30 Ohm. Another rod of the same mass and same material which has a diameter twice that of rod A is taken what is the resistance of rod B?
I want to know in the solution why is it taken that the density of both roads are same?
Dear Student ,
As the both rods are made of same material so their density in the solution are taken to be same .
