Answer 2

Answer:

26) B) I and III

27) D)10V

Explanation:

26) long wire and a solenoid have magnetic lines from north pole to south pole

27) A have potential 10 +20 =30ohm

B have potential 10+5=15 ohm

so restivity are in ratio 2:1

so, 30 V also divide in ratio 2:1

A=20 ,B=10

VA - VB=20 -10

=10 V
