Why more charge can be stored on a metal if it is highly polished than when its surface is rough?
The issue is not storing the charge but keeping it stored.
A charged object tends to ‘leak’ charge. After all, the charges “want” to leave… they are being repelled by all the other like charges, and leaving will cause them to release energy. Only the fact that it takes a lot of force and energy to break free of the surface of the metal keeps them from leaving.
Consider a conductive sphere with some charge on it. The charges arrange themselves evenly as possible on the surface of the sphere in order to maximize their distance from all other charges. Here is a 2D version, with arrows to show the field (and hence the force on each charge)

What is the formula for calculating the charge stored in a capacitor?
The formula for calculating the charge stored in a capacitor is Q CV, where Q represents the charge stored in the capacitor, C is the capacitance of the capacitor, and V is the voltage across the capacitor.
What is the effect of changing the distance between the plates of a capacitor on the charge stored on the plates?
Changing the distance between the plates of a capacitor affects the charge stored on the plates. As the distance decreases, the capacitance increases, leading to a higher charge stored on the plates. Conversely, increasing the distance between the plates decreases the capacitance and results in a lower charge stored on the plates.
What is the relationship between the electric potential in a capacitor and the amount of charge stored on its plates?
The electric potential in a capacitor is directly proportional to the amount of charge stored on its plates. This means that as the amount of charge stored on the plates increases, the electric potential also increases.
What is the relationship between the potential difference across a capacitor and the amount of charge stored on it?
The potential difference across a capacitor is directly proportional to the amount of charge stored on it. This means that as the potential difference increases, the amount of charge stored on the capacitor also increases.
What is the relationship between the voltage drop across capacitors and the amount of charge stored in them?
The voltage drop across a capacitor is directly proportional to the amount of charge stored in it. This means that as the charge stored in a capacitor increases, the voltage drop across it also increases.
What energy is stored in a battery?
It's all chemical energy with a small amount of surface charge.
Why are metal bodes designed to store charge made from large hollow spheres?
Large hollow spheres are used for metal bodies designed to store charge because they have a uniform electric field inside and the charges remain on the outer surface. This design minimizes the potential for internal charges to interfere with the stored charge, and it also maximizes the amount of charge that can be stored due to the large surface area of the sphere.
Drum of a photocopying machine of length 42cm and radius 6cmfind charge?
That's not enough information to find the charge. You can find out the surface area with that information, but to actually know the charge, you would also need to know how much charge is stored per unit area.
What is the formula for calculating the charge stored in a capacitor?
The formula for calculating the charge stored in a capacitor is Q CV, where Q represents the charge stored in the capacitor, C is the capacitance of the capacitor, and V is the voltage across the capacitor.
Can the electrostatic charge be stored?
It's always stored unless it's conducted away. Thus all insulators have & hold a static charge.

Why is phosphorus is stored In Water?
because it is highly reactive in nature & hence is stored under water

What is the maximum charge that can be stored on the capacitor?
The maximum charge that can be stored on a capacitor is determined by the capacitance of the capacitor and the voltage applied to it. The formula to calculate the maximum charge is Q CV, where Q is the charge, C is the capacitance, and V is the voltage.
