Explanation:
(1). Formula to calculate the potential difference is as follows.
= 
= 
= 
= 
= 38.7 volts
Therefore, magnitude of the potential difference between the two spheres is 38.7 volts.
(2). Now, formula to calculate the energy stored in the capacitor is as follows.
E = 
= 
= 
Thus, the electric-field energy stored in the capacitor is
.
Answer:
V = V0 + a t
V = 75 - 9.8 * 3 = 45.6 m/s
The answer is 2Hz
Using the formula f= 1/T we can plug in .5 for T and solve for frequency.
