    If a battery of 6V is connected to the terminals of 3m long wire of uniform thickness and resistance of the order of \[100\Omega \] The difference of potential difference between the two points separated by 50 cm in the wire is:

    A) 1V                   

    B) 1.5V    

    C) 2V                   

    D) 3V

    Correct Answer: A

    Solution :

    [a] \[I=\frac{V}{R}=\frac{6}{100}=\frac{3}{50}A\] Resistance 3m wire \[100\Omega \] Resistance of 50cm wire =\[\frac{100}{300}\times 50=\frac{50}{3}\Omega \] Potential difference between of two points \[=\frac{3}{50}\times \frac{50}{3}=1V\]
