Read the paragraph given below and answer the question.
Sutton and Boveri argued that the pairing and separation of a pair of chromosomes would lead to the segregation of a pair of factors they carried. Sutton united the knowledge of chromosomal segregation with Mendelian principles and called it the chromosomal theory of inheritance. Following this synthesis of ideas, experimental verification of the chromosomal theory of inheritance by Thomas Hunt Morgan and his colleagues, led to discovering the basis for the variation that sexual reproduction produced. Morgan worked with the tiny fruit files, which were found very suitable for such studies. They could be grown on simple synthetic medium in the laboratory. They complete their life cycle in a short span of time and a single mating could produce a large number of progeny flies. Also, there was a clear differentiation of the sexes - the male and female flies are easily distinguishable. Also, it has many types of hereditary variations that can be seen with low power microscopes.
Cross performed between yellow bodied, white eyed females and brown bodied red eyed males of Drosophila results in:

Two equal and similar charges 3 cm apart in air repel each other with a force of 1.6 N. What will be the magnitude of each charge?

Year(x)	2011	2012	2013	2014	2015	2016	2017
Sales (in lakh Rs. ) (y)	65	68	70	72	75	67	73

If \(y=70+0.964(x-2014)\) be a straight line trend fitted by the method of the least squares to the above data, then the trend value for the year 2015 is :

The graph shows the variation of potential difference between the plates of two capacitors A and B with the increase of charge stored by them. From the graph we can conclude:
