Answer: The outer loop should carry a current of 2.0 A.
The current should flow in the counter-clockwise direction
Explanation: Please see the attachments below
Answer:
d' = d /2
Explanation:
Given that
Distance = d
Voltage =V
We know that energy in capacitor given as



If energy become double U' = 2 U then d'



2 d ' = d
d' = d /2
So the distance between plates will be half on initial distance.
