EMF vs Potential difference

Electricity and Magnetism Level 2

A circular loop of radius $R$ is placed in a region of uniform time varying magnetic field $B=B_0t$ . The magnetic field is into the plane of the ring. There are two points $A$ and $B$ diametrically opposite to each other on the ring, as shown in the diagram.

What is the potential difference between points $A$ and $B$ ?

Details and Assumptions:

The circular loop has uniform thickness and resistivity.
$B_0$ is a constant and $t$ is time.
