66that's not correct richa (I think it was a wild guess, isn't it?)
A plane divides space into two halves. One half is filled with a homogeneous conducting medium and physicists work in the other. They mark the outline of a square of side a on the plane and let a current I_0 in and out at two of its neighboring corners using fine electrodes. Meanwhile, they measure the potential difference V between the other two corners. (see figure)
What is the resistivity of the homogeneous medium in terms of the given data?
