Q 1678478306.     Consider two different metallic strips (1 and 2) of the same material. Their lengths are the same, widths are `w_1` and `w_2` and thicknesses are `d_1` and `d_2`, respectively. Two points `K` and `M` are symmetrically located on the opposite faces parallel to the `x-y` plane. `V_1` and `V_2` are the potential differences between `K` and `M` in strips 1 and 2, respectively. Then, for a given current I flowing through them in a given magnetic field strength `B`, the correct statement(s) is (are)

(This question may have multiple correct answers)

A If `w_1 = w_2` and `d_1 = 2d_2`, then `V_2 =2 V_1`
B If `w_1 = w_2` and `d_1 = 2d_2`, then `V_2 =V_1`
C If `w_1 = 2w_2` and `d_1 = d_2`, then `V_2 =2 V_1`
D If `w_1 = 2w_2` and `d_1 = d_2`, then `V_2 =V_1`
