Figure shows two rings having charges Q and `- sqrt(5)Q`. Find potential difference a and B i.e. `(V_(A)-V_(B))`.

Potential difference across AB , i.e., V_(A)-V_(B) is

Potential difference between points A and B (i.e. V_(A) - V_(B) ) is -----

Potential difference between points A and B (i.e. V_(A) - V_(B) ) is -----

In the circuit as shown,the charge varies with time t as q=t^(3)-4 ,where q is in coulombs and t is in seconds.Where at t=2 , the potential difference between A and B, V_(A)-V_(B) in volts is
