I think you just need me to tell the steps.

1) For solving problem 971 , we first need to find the total resistivity

As the hint suggest we will have to double integrate the value. First wrt x and then wrt y.

d²F = di * dl* B

Here B is a constant , di varies as the V/ R_xy , l is the unit length at (x, y)

This integration will lead to the value of F.

As per the answer the value is

F = 7/2 V_ab B/rho

We can see that the dimension of this term is MLT^-2 , which nothing but the dimension of Newton.

Please write back in comment if you have any other doubt. I would be happy if you give a thumbs up if you like the answer.
