Direction: In the following question, a given questions is followed by information in three statements. You have to decide the data in which statement (s) is sufficient to answer the question and mark your answer accordingly. 8 people – A, B, C, D, E, F, G and H are sitting around a circular table at equal distances to each other facing towards centre (not necessarily in the same order), then how many persons are sitting between C and D, if counted from the left of D. C is sitting second to the left of F. Four persons are sitting between F and D. A is sitting fourth to the right of D. Two persons are sitting between A and E. B is sitting third to the right of G.

Consider the situation as shown in the figure. If m_(1)gtm_(2) , I is the moment of intertia about its axis of rotation, R is the radius of pulley. The objects are released from rest separated by a vertical distance 2 h . Find the translational speed of the objects as they pass each other. Assume no slipping.

Two circular metal plates each of radius 10 cm are kept parallel to each other at a distance of 1mm. What kind of capacitor do they make ? Mention one application of this capacitor. If the radius of each of the plates is increased by a factor of sqrt(2) and thier distance of seperation is decreased to half of its inital value, calculate the ratio of capacitance in the two cases. Suggest a possible method by which the capacitance in second case is increased to n times.

Six family members P, Q, R, S, T and U are sitting around a circular table facing towards the centre and at equal distance from each other (not necessarily in the same order). Q is to the immediate right of S. P and S are facing towards each other. T is not the neighbour of P. R is to the immediate right of P. Who are the neighbours of U?

A boy sitting on the top most berth in the compartment of a train which is just goint to stop on a railway station, drops an apple aiming at the open hand of his brother situated vertically below his hands at distance of about 2m. The apple will fall:-

10 friends (5 boys P, Q, R, S and T and 5 girls A, E, I, O and U) are playing a game and they are sitting in a circle. The distance between every two friends is equal. Two boys and two girls are facing opposite to the centre of the circle and other 6 friends are facing towards the centre of the circle. A is the fourth to the left of O, who is third to the right of P. R is second to the right of T, who is not near to E. There are three friends between I and R. S is second to the left of U and facing the centre of the circle. P and E are sitting opposite and facing each other. I is second to the left of Q. A is facing opposite to the centre of the circle. More than three boys or girls are not sitting together. Not more than two friends who are facing opposite to the centre of the circle are sitting together. Which of the following boys is not sitting between girls ?
