A point charge q = - 8.0 nC is located at the origin. Find the electric field vector at the point x = 1.2 m, y = -1.6 m.

In class 12 there are 8 students. In class 11 there are 6 students .In class 10 there are 5 students . Total ways of selecting 10 students , such that there are at least 2 students from each class and at most 5 students from 11 students of Class 10 and 11 combined is 100k. Then find value of k

There are 5 students in class 10, 6 students in class 11 and 8 students in class 12. If the number of ways, in which 10 students can be selected from them so as to include at least 2 students from each class and at most 5 students from the total 11 students of class 10 and 11 is 100 k, then k is equal to _______.

Ratio of First ,Second and Third Class train fares between two stations was 8:6:3 .First Class and Second Class train fares are reduced by 1/6 and 1/12 repectively .Ratio of no of passengers in first, second and third class in a year is 4:9:24 .From a stattion total sale of ticket of Rs. 355600 .First the amount collected from first class .

Railway fares of 1st, 2nd and 3rd class between two stations were in the ratio of 8 6 : 3. The fares of 1st and 2nd class were subsequently reduced by 1/6a n d1/(12) respectively. If during a year the ratio 12 between the passengers of 1st, 2nd and 3rd classes was 9 :12 : 26 and the total amount collected by the sale of tickets was Rs, 1088, then find the collection from the passengers of 1st class.
