3. (02.03 MC) Two ticker tape results are shown:
Which statement accurately describes the motion of the objects in the ticker tape above? (2 points)
o
Both objects are speeding up at a constant rate.
One object speeds up before it slows to a stop.
Both objects speed up before stopping.
O
One object speeds up at a constant rate until it stops.

C).

Explanation:

As we know that capacitance of a given capacitor is

now we know that energy stored in the capacitor plates

here if all the dimensions of the capacitor plate is doubled

then in that case

here area becomes 4 times on doubling the radius and the distance between the plates also doubles

So new capacitance is now

so capacitance is doubled

now the final energy stored between the plates of capacitor is given as

so the final energy is
