Aparallel-plate capacitor has square plates that are 8.00 cm on each side and 3.80 mm apart. the space between the plates is completely filled with two square slabs of dielectric, each 8.00 cm on a side and 1.90 mm thick. one slab is pyrex glass and the other is polystyrene. if the potential difference between the plates is 86.0 v, how much electrical energy is stored in the capacitor?

The electrical energy is stored in the capacitor is .

Explanation:

Given that,

Side = 8.00 cm

Distance = 3.80 mm

Potential difference = 86.0 V

We need to calculate the capacitance of polystyrene

Using formula of capacitance

Put the value into the formula

We need to calculate the capacitance of Pyrex glass

Using formula of capacitance

Put the value into the formula

We need to calculate the capacitor

Using formula of capacitor

We need to calculate the electrical energy is stored in the capacitor

Using formula of stored energy

Put the value into the formula

Hence, The electrical energy is stored in the capacitor is .

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
