Answer:
emf will also be 10 times less as compared to when it has fallen
Explanation:
We know, from faraday's law-
and
So, as the height increases the velocity with which it will cross the ring will also increase.
Given
Now, from
From equation a and b we see that velocity when dropped from is 10 times greater when height is 40 so, emf will also be 10 times less as compared to when it has fallen

Answer: option B
Explanation: The sampling error also known as the marginal error is given mathematically as
Margin of error = critical value × (standard deviation/√n)
Where n = sample size
As we can see from this formulae, the only variable here is the margin of error and the sample size.
Hence margin of error = k/√n
Which implies that there is an inverse relationship between margin of error and sample size.
A large sample size gives a low margin of error while a small sample size gives a large margin of error.
