Answer:
The charge flows in coulombs is

Explanation:
The current magnitude of current is given by the resistance and the induced Emf as:



,
,
,
Ω
,
Replacing :


Distance , d = a+b

The unit of d is in meter and t is in seconds.
So the unit of a a must be meter.
Now we have unit of b

is meter.
So unit of b*

= meter
Unit of b = meter/

So unit of a = m and unit of b = m/
