Write any three properties of electric charge.
Ans: 1. Additivity of charges: The total charge of a system is the algebraic sum of all individual charges in the system.
ii. Conservation of charge: The total charge of an isolated system remains unchanged with time.
iii. Quantisation of charge: The total charge of a body is always integral multiple of a basic quantum of charge 'e' ie. q±ne
iv. Like charges repel and unlike charges attract each other.
2. State and explain Coulomb's law in electrostatics.

Generic Class Example:class MyBox<T>
{
public T Value;
public void Show() => Console.WriteLine(Value);
}
class Program
{

{
/** MyBox<int> b1 = new MyBox<int> { Value = 100 };
/**MyBox<string> b2 = new MyBox<string> { Value =
1.A medical prescription includes the date, patient identification (such as name, age, and weight if relevant), the Rx symbol (meaning "take"), the inscription (drug name, strength, dosage form, and quantity), the subscription (instructions to the pharmacist), the signatura or "Sig." (directions for the patient including route, frequency, and duration), the prescriber's information (name, signature, license number), and refill instructions. Units of measurement include micrograms (µg), milligrams
A chronic inflammatory disease of medium and large arteries, caused by endothelial injury and lipid accumulation. Key risk factors: hypertension, hyperlipidemia, smoking, diabetes. Lesions evolve from fatty streaks → fibrous plaques → complicated plaques. Complications: MI, stroke, aneurysm, peripheral artery disease. Histologically shows lipid cores, calcification, and fibrous caps.
Chronic BP elevation causes vascular and
Gross Morphology: Localized area of liquefactive necrosis filled with yellow pus, surrounded by a thin fibrous capsule and edematous, inflamed brain tissue.
Pathology: Caused by hematogenous spread of bacterial infection, direct trauma, or contiguous spread (e.g. from sinuses). Represents focal suppurative inflammation of the brain.
Gross Morphology: Well-circumscribed, encapsulated globoid mass with a soft, tan “fish-flesh” appearance, often
4. Explain EC Security requirements.
E-Commerce security involves multiple requirements to ensure the safe operation of online transactions. These include Confidentiality (ensuring only authorized parties can view data), Integrity (data is not altered during transmission), and Authentication (verifying identities of users or systems).
Other requirements are Non-repudiation (neither party can deny a transaction), Availability (services must be accessible when needed), and Privacy (protecting personal
*Business Planning:*
Business planning is the process of defining a company's objectives, goals, and strategies, and outlining the actions and resources required to achieve them. It involves analyzing the current situation, forecasting future trends, and developing a roadmap for the organization's future direction.
