Answer 2

see the figure and solve it

And give it's explanation..​

• Option A is correct.
• From the figure it's clear that,
• a compound wire is thicker at point O than the other end of the wire.
• we have a formula for current,
• I = V/R
• implies that, the current is inversely proportional to the resistance.
• And we even know that,
• the thicker the wire, higher is the current for a given voltage and hence the lower resistance.
• Hence, the resistance increases as the distance increase from point "O" till the other end of the compound wire.
• The graph in option A represents the increase in resistance with the increase in distance x.
