Q No. 2: Five people in a community with stable population of 5000 people got infected with a contagious disease (such as covid 19). A theory of epidemic spread postulates that the rate of change in the infected population (number of people) is proportional to the product of the number of people who have the disease with the number that are disease free (take the constant of proportionality as 6.0 x 104). Assuming the theory is correct, how long will it take 75% of the population to contract the disease? (Assume the community as a closed system with nobody goes out or comes in but they are free to meet each other).

Differential Equations

Have you ever observed the movement of the satellites and rockets or how the planets go around the sun in their orbits? How will you determine their motion? Definitely they follow some scientific laws and these kinds of problems are framed as differential equations.

Question

Q No. 2: Five people in a community with stable population of 5000 people got infected with
a contagious disease (such as covid 19). A theory of epidemic spread postulates that the rate
of change in the infected population (number of people) is proportional to the product of the
number of people who have the disease with the number that are disease free (take the
constant of proportionality as 6.0 x 104). Assuming the theory is correct, how long will it take
75% of the population to contract the disease? (Assume the community as a closed system
with nobody goes out or comes in but they are free to meet each other).
