Direction: Read the following text and answer the following questions on the basis of the same:
Polio drops are delivered to 50K children in a district. The rate at which polio drops are given is directly proportional to the number of children who have not been administered the drops. By the end of 2nd week half the children have been given the polio drops. How many will have been given the drops by the end of 3rd week can be estimated using the solution to the differential equation dy/dx = k(50 - y) where x denotes the number of weeks and y the number of children who have been given the drops.
Q. The value of C in the particular solution given that y(0) = 0 and k = 0.049 is
  • a)
    log 50
  • b)
    log 1/50
  • c)
    50
  • d)
    -50
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
Direction: Read the following text and answer the following questions...
Given,
y(0) = and k = 0.049
We have, -log|50 - y| = Kx + C
log |50 - y| = -Kx - C
log |50 - 0| = 0 - C
[∵ x = 0, K = 0.049, y(0) = 0]
log 50 = - C
C = log 1/50

Given Information:
The rate at which polio drops are given is directly proportional to the number of children who have not been administered the drops.
By the end of the 2nd week, half the children have been given the polio drops.

Differential Equation:
We are given the differential equation dy/dx = k(50 - y), where x denotes the number of weeks and y denotes the number of children who have been given the drops.

Particular Solution:
To find the particular solution, we need to find the value of C.
Given y(0) = 0, which means at the beginning (x = 0), no children have been given the drops.

Substituting the given values:
Substituting x = 0 and y = 0 in the differential equation, we get:
dy/dx = k(50 - y)
0 = k(50 - 0)
0 = 50k

Solving for k:
From the above equation, we can see that k = 0.

Substituting the value of k:
Now, substituting the value of k = 0 in the differential equation, we get:
dy/dx = 0(50 - y)
dy/dx = 0

Integrating both sides:
∫dy = ∫0 dx
y = C

Substituting the value of y(0) = 0:
We know that y = C, so substituting the value of y(0) = 0, we get:
0 = C

Conclusion:
Therefore, the value of C in the particular solution is 0.
