23)Physics |A material of resistivity ρ is formed in the shape of a truncated cone of axial length L

The left end has a radius "a" while right end has a radius "b". Assuming a uniform current density through any circular cross-section of the cone, find the resistance between the two ends. Physics | Current Electricity | JEE Adv | resistance of a tapered rod and drift speed at two points in a rod
