since there is no terminal voltage in the first battery
0=Emf -Ir1
Emf=Ir1
to find the terminal voltage of the second battery
Vt= Emf-Ir2
substitute the value of emf
Vt= Ir1-Ir2
the terminal voltage is equal to the voltage in resistor R
IR= Ir1 - Ir2
taking I common
R=r1-r2
b is the answer

Thanks for the excellent video sir. For question 36 option A ( minute 6.00 ), why did you calculate the resistance from P to R instead of the resistance from P to Q? Please correct me if I'm wrong sir.

q35. 6 + 3 = 11? is that a mistake you made while going through it quick or am i missing somehting?

He corrected afterwards 6+3=9 , you can see this at 19:16

[@Muhammadkhan-jw7zo]

in Q 5, 34 on slide in equation 15-9= -i3 +i1. It was if we consider the loop clockwise but if we consider the loop anticlockwise. It would be 15-9=-i1+i3. Then according to that ans b is right. What is wrong in considering anticlockwise loop.

You didn’t reverse the sign of emfs on LHS. it will be 9-15
