Frequency = 1 / (2π√LC)
Frequency = 1 / (2π · 2.8 x 10⁻⁴ · C)
Frequency = 1 / (1.759 x 10⁻³ · C)
<em>Frequency = (568.4 / C) Hz.</em>

Energy stored in a capacitor = 1/2 C V²
Energy = 1/2 C · 2.25 x 10⁴
<em>Energy = (11,250 · C) Joules</em>

Neither of the answers can be completely specified without knowing the value of the capacitor.

Answer: acceleration due to gravity of planet a would be twice that of planet b. Given that the radius are thesame.
Explanation:
Acceleration due to gravity is as a result of the gravitational force of attraction of a planet to its centre.
g = GM/r^2
Where;
g = acceleration due to gravity
G = gravitational constant
M = mass of planet
r = radius of planet
Given that the two planet have the same radius, if the mass of planet a is twice the mass of planet b the the acceleration due to gravity of planet a would be twice that of planet b, because acceleration due to gravity is directly proportional to the mass of the planet.
