'N' is labelled 'runoff'. That's when the water is down. Streets are wet, worms come out of the ground, and water flows down the street to the sewer.
The only reasonable choice from this list is choice-A.
You can find the emf of the battery by using:
Q = CV.
Q = Charge in capacitor plates = 30μC
C = Capacitance of the capacitor = 30μF
V = Q/C = 30/30 = 1V
Ans: The emf of the battery = 1V.
Answer:
Will experience a force due to electric field.
Explanation:
- When a free negative charge is released in an electric field it experiences a force due to the electric field in a direction opposite to the direction of the magnetic field.
According to Coulomb's law this force is mathematically given as:
and, electric field due to a charge is given as:
where:
permittivity of free space
q = magnitude of charge
r = radial distance from the charge
