Answer:
Explanation:
From the free-body diagram for the car, we have that the normal force has a vertical component and a horizontal component, and this component act as the centripetal force on the car:
Solving N from (2) and replacing in (1):
The centripetal acceleration is given by:
Replacing and solving for v:
Answer:
C) Both the charge on the plates of the capacitor and its capacitance would change.
Explanation:
The capacitance of parallel plate capacitor without dielectric material is given as;
A parallel plate capacitor with a dielectric between its plates has a capacitance given by;
where;
C is the capacitance
K is the dielectric constant
ε₀ is permittivity of free space
A is the area of the plates
d is the distance of separation of the two plates
Again, Q = CV (without dielectric material)
(with dielectric material)
Finally, we can conclude that both the charge on the plates of the capacitor and its capacitance would change.
