Answer

1. False; 2. N/C or V/m; 3. Positive to Negative; 4. Electric Potential; 5. V = \frac{W}{Q}; 6. Sharp Points; 7. Equipotential Lines; 8. Redistribution of charge due to nearby charges; 9. F \propto \frac{1}{r^2}. Explanation 1. Determine the charge on a body losing electrons A body that loses free electrons becomes positively charged. Therefore, the statement is **False**. 2. Identify units for electric field strength Electric field strength is measured in **Newtons per Coulomb (N/C)** or **Volts per meter (V/m)**. 3. Direction of electric lines of force Electric lines of force flow from **positive to negative charges**. 4. Define work done on a unit positive charge The term is **Electric Potential**. 5. Write equation for potential difference The potential difference V is given by **V = \frac{W}{Q}**, where W is work done and Q is charge. 6. Location of static charge concentration Static charge is most concentrated at **sharp points** on a solid object. 7. Name of lines connecting points with same potential These lines are called **Equipotential Lines**. 8. Define induction Induction is the process of **redistributing electrical charge in an object, caused by the influence of nearby charges** without direct contact. 9. Relationship between force and distance in Coulomb's law According to Coulomb's law, the force F between two charges is inversely proportional to the square of the distance r between them: **F \propto \frac{1}{r^2}**.
