Answer:
c. Smaller than.
Explanation:
The energy stored in a capacitor is given as
E = 1/2CV²...................... Equation 1
Where E = Energy stored in a capacitor, C = capacitance of the capacitor, V = Voltage.
Also,
C = εA/d ......................Equation 2
Where ε = permitivity of the material, A = cross-sectional area of the plate, d = distance of separation of the plate.
substitute equation 2 into equation 1
E = 1/2εAV²/d ................. Equation 3
From equation 3 above,
The energy stored in a capacitor is inversely proportional to the distance of separation between the plates.
Hence when the plate is pulled apart by a distance D (D>d) The energy stored in the capacitor will be smaller.
The right option is c. Smaller than.
