The degree of 3 is:
The degree of a polynomial is the highest power of the variable in the given expression. Given Expression: 3 Since 3 is a constant, it can be written as: 3 = 3x⁰ where x⁰ = 1. Step 1: Identify the Degree A constant term always has a degree of 0, because it does not contain a variable. Final Answer:Read more
The degree of a polynomial is the highest power of the variable in the given expression.
Given Expression: 3
Since 3 is a constant, it can be written as:
3 = 3x⁰
where x⁰ = 1.
Step 1: Identify the Degree
A constant term always has a degree of 0, because it does not contain a variable.
Final Answer: The degree of 3 is 0, so the correct option is : (a) zero.

A charge Q is placed at the centre of the line joining two charges q and q. The system of three charges will be in equilibrium if Q is
For the system to be in equilibrium, the net force on each charge must be zero. By applying Coulomb’s law and balancing forces symmetrically, the required charge Q at the center must be -q/4 to counteract the repulsion between the two q charges. Answer: (d) -q/4.

Two point charges + 16 q and – 4 q are located at x = 0 and x = L The location of the point on x-axis at which resultant electric field due to these charges is zero is
The resultant electric field is zero where the fields due to +16q and -4q cancel each other. By using Coulomb’s law and setting the field magnitudes equal, solving for distance gives x = 4L from the charge +16q (toward the right). Answer: (c) 4L.
