Please solve RD Sharma Class 12 Chapter 21 Differential Equations Exercise Case Study Based Question (CSBQ) Question 1 Subquestion (iii) maths textbook solution.
Answer: option(c)
Hint: Try to understand the given equation is whether of linear or non- linear or homogeneous.
Given: Differential equation in r and t
Solution: obtained differential equation
The above formed equation is of the order 1st. So, it is a first order differential equation.
It is of non – linear type and variable can be separated.
“So it is first order non- linear differential equation in variable separable form”.
Note: Linear equation is in the form of
While homogeneous equation is having same degree.
