Answer:
Explanation:
Step 1
Phosphoric Acid is a triprotic acid where H3PO4 dissociates to H2PO4- which then further dissociates HPO42- and it then forms PO43-. Equation for acid dissociation constant for the dissociation of H3PO4 and HPO42- can be written as above.
Step 2
Concentration of H2PO4- produces during the dissociation of H3PO4 can be determined by constructing an ICE table.
Step 3
Concentration of HPO42- produces during the dissociation of H2PO4- can be determined

The given data is as follows.
Magnetic field (B) = 0.30 T
Current (I) = 24 A
n =
charge on electron (e) = C
Formula to calculate the potential difference is as follows.
V =
=
= V
Therefore, we can conclude that value of potential difference is V.
