Answer:
a) 0.21N/C
b) counterclockwise
Explanation:
a) to find the magnitude of the electric field you can use the following formula:

A: area of the ring = pi*r^2
E: electric field
Ф_B: magnetic flux
In the line integral you can assume E as constant. Furthermore, you calculate the change in the magnetic flux by taking into account that the time interval is 1.12/0.21=5.33s. By replacing in the formula you obtain:


the magnitude if the induced electric field is 0.21N/C
b) By the Lenz's law you can conclude that the current has a direction in a counterclockwise
