Answer:
The induced emf in the loop is 
Explanation:
Given that,
Length of the wire, L = 1.22 m
It changes its shape is changed from square to circular. Then the side of square be its circumference, 4a = L
4a = 1.22
a = 0.305 m
Area of square, 
Circumference of the loop,

Area of circle,

The induced emf is given by :

So, the induced emf in the loop is 
Answer:
If one cup falls down then there will be 59 cups left.
